Thanks fr a bug report. It seems to me the window is there, only not painted properly. Could you try for example a `gtk4-demo` application, whether it'll be affected in a similar way, please? I faced something similar in GNOME OS, as reported here: https://gitlab.gnome.org/GNOME/gnome-build-meta/-/issues/878 but it was in the GNOME itself. I cannot tell whether the two are related.

Yes, same problem with gtk4-demo. By the way, if I do `ssh -X` to the virtual machine and try to start gnome-software or gtk4-demo with X forwarding via ssh, then it does not work either, a window opens but no contents are drawn. And the terminal shows this error messages: mfabian@f41:~$ gtk4-demo libEGL warning: DRI3: Screen seems not DRI3 capable libEGL warning: DRI2: failed to authenticate libEGL warning: DRI3: Screen seems not DRI3 capable MESA: error: ZINK: failed to choose pdev libEGL warning: egl: failed to create dri2 screen **All** Gtk4 applications seem to have this problem, gnome-text-editor as well. Thanks for the update. I'm moving this to the gtk4 for further investigation. Could you provide the gtk4 package version you've installed, please? > Could you provide the gtk4 package version you've installed, please?

It also does not work when using `su -` to become root and then trying to start a gtk4 program

From https://gitlab.gnome.org/GNOME/gtk/-/issues/6840#note_2206428 The following is the workaround. env GSK_RENDERER=cairo gnome-text-editor I updated my f41 virtual machine again today. I can start gtk4 programs on XFCE now, and I can do `ssh -X` to the virtual machine and start a gtk4 program. But the problem still exists when using `su -` to become root and then trying to start a gtk4 program.

If that's a regression maybe better to open a separate bug for that. I think the main issue is fixed so it would be reasonable to close this issue already. |
