Description

[Joel Maher ( :jmaher ) (UTC -8)]

when running tests in CI on a newer version of linux (18.04 -> 24.04) we run into some new perma failures.

in this opt log, you can see these failure:

this bug will be for tracking investigations, I will be skipping these tests in a manifest in a larger patch to green stuff up.

[Mark Striemer [:mstriemer]]

Looks like there is some code to special case Linux already, but these failures are before those checks. On my Ubuntu 22.04 I get windows that are 52px too big (width and height--although checking the content window size it appears to be correct), these failures have them as 37px too short...

Looks like you added these tests Emilio, any ideas?

Comment 2

[Emilio Cobos Álvarez [:emilio]]

Yes, this should probably move to widget: GTK

I can reproduce this failure with MOZ_GTK_TITLEBAR_DECORATION=none, but not with the default settings on Gnome + X11, can you confirm that?

This is probably related to bug 1431429, where we don't allow CSD decorations on automation. I guess once we update to 22.04 I can try to re-land that.

Comment 3

[Mark Striemer [:mstriemer]]

I believe on Monday my Ubuntu VM was 22.04 and stock Gnome/Wayland and it was failing. I have since updated to 24.10 Gnome/Wayland and it also fails. That looks like an environment variable? Exporting it as none/client/system and running the test seems to have no effect, although perhaps it's X11 only?

Comment 4

[Joel Maher ( :jmaher ) (UTC -8)]

the bug was originally filed for x11. maybe it fails in both wayland and x11.

Comment 5

[Emilio Cobos Álvarez [:emilio]]

Yeah, it's X11 only. You need MOZ_ENABLE_WAYLAND=0 for it to take effect.
