(server: xpra 3.0.3 on RHEL, client: xpra 3.0.3 on Win10)
I have a Java/Swing/Batik based tool that controls some electronic
hardware. When I click on certain components, a popup window should appear -- but it does not. The tool does not work without hardware attached to the workstation so I can't share it and don't know of a way for someone else to reproduce this problem.

I noticed that behavior before updating xpra to 3.0.3 (some 3.0.1 or 3.0.2 versions) and hoped the update might fix it, but it doesn't. I also tried a version 2.5.2 client (don't know an easy way to switch server versions...) and it behaves the same.
The popup does not appear when it should but an icon on the windows taskbar appears, indicating that there should be a popup. I minimized all windows to make sure that the popup is not hidden behind one of them.
The popup appears when I use cygwin/xwin connection to the RHEL workstation instead of xpra.

The "-d window" output when the popup is meant to show up is like this:

I have a Java/Swing/Batik based tool that controls some electronic
Java applications are notoriously bad at following X11 conventions. We have a number of workarounds for them already.

From your log, the window definition is here:

<class 'xpra.client.gl.gtk3.nativegl_client_window.GLClientWindow'>\
    (gtk3.client, <__gi__.GdkWin32Window object at 0x000000002e7dfd40 (GdkWin32Window at 0x00000000033a9af0)>, \
    0, 33, 479, 1345, 203, 204, 203, 204, {
      b'size-constraints': {b'position': (479, 1345), b'gravity': 1}, b'xid': b'0x60029d', b'title': b' ', \
      b'pid': 61725, b'client-machine': b'xxxxxxxx', b'icon-title': b'Java', b'group-leader-xid': 6292118, \
      b'window-type': (b'DIALOG',), b'decorations': 0, b'skip-taskbar': True, b'class-instance': (b'sun-awt-X11-XDialogPeer', \
      b'org-eclipse-jdt-internal-jarinjarloader-JarRsrcLoader'), b'set-initial-position': True}, \
      False, {}, WindowBorder(False, 0xD41D8C, 0.6, 5), (32767, 32767), 
      [4096, 2048, 16, 16, 7, 7, 1, b'\xff\xff\xff\xff\xff\xff\xff\xff...xff', b''], 0)

The window geometry sent by the server is: 479, 1345, 203, 204.
And the application is telling us to honour the initial position: 'set-initial-position': True is in the metadata.
That's 203x204 size at position 479,1345.
Is your client display big enough for that?
Do you start your application before connecting?
If so, does it work any better if you start it afterwards?
Does it help if you turn off opengl?
Can you attach the picture from xpra screenshot?
Maybe also attach the -d window,geometry,draw log output.

Tried a few things and it looks to me like the problem is about decorated/undecorated windows. I made a small sample program (attached) that I run with

javac Popups.java 
java Popups

When run through xpra, only the decorated popup shows up.

I've tried your example on Linux, MacOS, Windows 7 and Windows 10, and even with the html5 client.
Both windows showed up everywhere.

So there must be something different about your setup.

Please clarify:

• the resolution you are running at
• the exact build you are running (in full, not just the version)
• have you tried toggling opengl on or off?

With --opengl=no the non-decorated window DOES show.
Here are the startup messages (with OpenGL enabled). I think they contain what you asked for:

With --opengl=no the non-decorated window DOES show.
I can reproduce this on a system with an nvidia card.

And now I can't!

I'm not sure if it is the same bug, but running your example I also see some problems registering clicks.
It seems that sometimes the clicks go through the window with the two buttons and land somewhere else on the virtual screen. but not on the window it is intended for. Sometimes as if the window-relative pointer coordinates were used as absolute values.
Very strange since all other applications work fine.

Bisecting with python2 builds:

• v1.0.x OK
• v3.0.3 bad
• v2.0.x OK
• v2.3.x not sure - seen the bug, seen a click through the window
• v2.4.x bad
• v2.2.x OK

So somewhere between 2.2 (17607), 2.3 (19246) and 2.4 (r20681):

• r17500 OK with python2 client only (will need to bisect again with the client?)
• r20681 bad
• r19000 OK-ish? when moving the pointer quickly over the buttons, the first click does not register.. would be good to fix that one too
• 19800 OK-ish?
• r20200 OK-ish?
• r20400 bad
• 20300 bad
• r20250 OK-ish
• 20275 bad
• r20264 bad
• r20257 bad
• r20253 bad
• r20251 OK-ish
• r20252 bad

And so this is caused by relative pointer data. But why?

I think the click-through effect with the python3 builds is because with GTK3 passes we receive the click events on the window title bar and those should not be propagated to the server.

The bug I was chasing seems to have gone away completely on its own!? Maybe a system update fixed a buggy library? (will try again on a different system)

So, back to the original bug in this ticket - recap: only occurs with opengl enabled, only on win32, only with python3 builds, only with undecorated windows!

Comparing with and without opengl, the popup window metadata looks unremarkable (as per ticket description).
So then I updated the test apps to run native under GTK3 (r24723), and it turns out that GTK3 is just buggy on win32 with undecorated windows: when you toggle the "decoration" flag off and then on again, the window does not regain its decorations or at least they are not being re-drawn, but the pointer events are adjusted... so they land with an offset.
Running the same example through xpra: the window disappears as soon as we try to remove the decorations!
(also spotted another bug: #2516)

So r24725 fixes this by not using opengl for undecorated windows and re-initializing the window when the "decorations" flag is toggled. (backport to v3 in 24727)
@wolfram: there are beta builds with this fix here: [https://xpra.org/beta/windows].
Please close this ticket if that works for you.

Undecorated windows work in Xpra-Python3-x86_64_4.0-r24725 (I only updated the client), both in my litte sample program and in the electronics-control-tool where I intially saw the problem. Thanks for fixing this!
I am little concerned about moving to 4.0 because of the I-beam cursor problem that I mentioned here [https://xpra.org/list/2019-November/002440.html]. But strange enough I don't get that kind of mouse-cursor in eclipse editor-windows any more, so I can't check this right now.

You can switch back to the 3.0.x stable branch once 3.0.4 once is released with this fix.
The cursor problem was probably this bug: #2498 (regression which is now fixed in v4).

[totaam]

Could it still be happening with 3.0.4? See #2466#comment:13

Problem still exists in 3.0.4 because the backport had been applied to the wrong location (the dumb 'patch' command strikes again), 24922 fixes that.

There's a 3.0.5-RC build in the beta area: [https://xpra.org/beta/windows].

Updating the stable server, I'm still using xpra v3.0.4-24778.

Trying to then connect with the 3.0.5-24922 client from the windows beta repo, the connection fails with this output client side.

'POSIX'?

I'll try some of the other 3.0.5 builds and see if any work. I'm not certain I recall how to install a 3.0.5 in the beta repo on the Fedora server, when a dnf update with the beta repo enabled will likely install 4.0 instead... but if I have sudden recall of the syntax I'll try that as well.

As an added bonus, when I realized the client was hung. rather than crashed... and used control-c to kill from the cmd window, I got a little extra traceback, which might be useful.

Well, tried the 3.0.5-24827 client too, but checking your comment before typing makes it unsurprising that the chromium-browser should still be failing to display with that.

I won't bother with any of the earlier 3.0.5 clients.

A hint on the dnf syntax to install a 3.0.5 build rather than 4.0 from beta (dnf list xpra ... dnf install ?) would help also if the server needs any update (I get the feeling it shouldn't?).

Thanks for trying.

Damn, sorry about that.
That had already been fixed in 24926, but I had not uploaded a new build since... (I'm on a 4G metered connection this week)

Yeah, that's been happening for a while, I should fix it, again: #1899.

I got a little extra traceback, which might be useful.
Cool, probably a result of the forced shutdown, this should fix it: r24929.
(will backport)

I'm not certain I recall how to install a 3.0.5 in the beta repo on the Fedora server, when a dnf update with the beta repo enabled will likely install 4.0 instead
Can I force dnf to install an old version of a package?
(there may be more to it than that if the dependencies also need a downgrade..)

Found a Fedora 30 xpra v3.0.5-24928 build.
Launched with the usual command, and now the Python3 3.0.5-24827 windows client is able to connect, but unfortunately it is still not displaying the chromium-browser window when I try to launch from an xterm.

The logs look the same to me as what I posted in #2466, but in case there's a difference, here're the client-side output with a -d window when launching the chromium-browser.

Also (and I'll also mention this in #1797), it looks like something is causing a connection hang and timeout for the Chrome 79 html5 client on both Windows and OSX, using both http (http://10.0.3.148:1237) and https (https://10.0.3.148:1239), and only seem to be outputting the "usual" cert error messages server side (the ones I expect because I am just using a self-generated cert with no SAN despite Chrome's expectations).

That's the undecorated window bug.

Launched with the usual command, and now the Python3 3.0.5-24827 windows client is able to connect, but unfortunately it is still not displaying the chromium-browser window when I try to launch from an xterm.
You need the "real" 3.0.5 stable release for windows: 24928, or later if I re-issue it for the html5 connection bug. (24827 is too old and does not have the 24926 fix).
I am really hoping that this fix is correct as I won't be able to test it until I have access to a real desktop PC with a real GPU in it.

At last, a break.

3.0.5-24942 Windows client against a 3.0.5-24939 fedora 30 server... with opengl enabled despite being on the greylist... and the chromium-browser is displaying!

We'll just assume that will also work with any other applications with undecorated windows... and I'll close this again.
