client:

Xpra GTK3 client version 2.5-[r21454](../commit/5562fb4144e749efb368ee3bf0c242bfb03675be) 64-bit

server

Xpra GTK2 X11 server version 2.5-[r20740](../commit/55aec5ad7f3124f01d76970a91b1fbeba8cee82f) 64-bit (python2, I assume)

When I right-click the title bar of the window (trying to minimize it), client "window" completely freezes. Client window works normally otherwise i.e. I see the mouse pointer moving on :0.2 (projected on :0.0, #2131), even though mouse is hovering on the windows right-click menu.

What OS for client and server?

Clicking on a window title bar is not handled by xpra but by the client OS, so I don't understand why this would be an xpra bug.

I understand that. However, it doesn't seem to be happening with py2 builds.

I'm not seeing any problems here.
Does it do that with any application window? Even an xterm?
Have you tried disabling opengl in the client?
I've uploaded some newer builds, maybe a GTK library update fixed something - worth a try.

"Simple" windows don't freeze like that.
Either multiple windows from the same process or from "Run Command"'

Have you tried disabling opengl in the client?

Command lines:

"C:\Program Files\Xpra\xpra_cmd" shadow ssh://user@ip/0 --opengl=no --desktop-scaling=0.75 --clipboard=no
"C:\Program Files\Xpra\xpra_cmd" start ssh://user@ip/ --clipboard=no --webcam=no --speaker=off --microphone=off --opengl=no --start=gnome-terminal --start-new-commands=yes

But --opengl=no doesn't seem to make a difference

I've uploaded some newer builds, maybe a GTK library update fixed something - worth a try.

Xpra-Python3-x86_64_Setup_2.5-r21547 still has the issue.

I really cannot reproduce any problems with either "shadow" or "seamless" mode.

Maybe you can try turning options off until the problem disappears?
My number one usual suspect would be clipboard sharing.
