dash-to-dock Intelligent autohide glitches while entering in firefox full screen

[denilgabani]

While we go to the edge of screen in Firefox full screen When Intelligent auto hide is enabled it flickers continuously.
OS: Manjaro Linux
Gnome Version: 42.4

It flickers only in GNOME Wayland not in Xorg.

I also experience this issue.

Maybe duplicate of #1381.

Disable hardware acceleration of Firefox may workaround this bug. Could it be a bug of GNOME (when an app with hardware acceleration is in full screen and some multi-screen stuff...)?

Interesting that you mention that. Intelligent hiding of the top bar via an extension also expresses similar behavior.

Well here I cannot trigger dock out when Firefox/Chromium is in fullscreen mode (F11) without attaching to external monitor. I find dock glitches when these conditions satisfy:

• Firefox/Chromium is in maximum window in laptop screen
• The "dock" is in laptop screen
• The GNOME "top bar" is in external screen

However if disabling hardware acceleration works in your case, I believe that it's the same bug as issue 1381.

Update 1: GNOME Web also makes the dock glitches.

For developers to reproduce this bug, this is how I position my displays:

Disabling FF hardware acceleration works around the issue. Unlike others, this is problematic even on a single display for me.

So this bug exists on display with dock and without top bar (by other extensions, or in multi-display environment)...

suffering the same thing

The best solution I found is to move to Xorg as it is working in XOrg perfectly😔.

According to #1868 and https://www.reddit.com/r/gnome/comments/ye9yzu/dash_to_dock_flickering/, Meta.disable_unredirect_for_display(global.display); can workaround this problem, and it works on my laptop.

Disabling unredirection may hurt full-screen games performance, I guess that's why mutter enables that by default. However, I have tested supertuxkart and firefox (F11) and I find that the dock will NOT be triggered out when it is actually in fullscreen mode. As apps all use CSD in GNOME wayland, I guess that when an app gets maximized in a display without any gnome-shell decorations, mutter thinks that it should use undirection for that app, and this behavior of mutter brings out the bug of dash-to-dock.

Maybe people familiar with mutter could file an issue/merge request to that (it may be related to funciton find_scanout_candidate() for wayland and maybe_unredirect_top_window() for xwayland (?))? Or, dash-to-dock may kindly ask mutter to disable unredirection before it pops out in this situation, and when it hides again asks mutter to enable unredirection...

I'm also suffering this problem. First I thought it was a problem with the 'Hide Top Bar' extension, but it was Dash to Dock with autohide enabled and fullscreen apps (ie. Ardour or Blender).

The trick from redit works temporarily:
Alt+F2, lg and then enter Meta.disable_unredirect_for_display(global.display)

This extension is out there to automate the aforementioned workaround.

Did you guys find any issues after disabling unredirection on wayland? Tried a few games, don't really see performance problems.
