Hello @yoyobuae, in general, not OpenGL application should be capable of taking down your desktop environment. This reads like an issue that should be mentioned to the package maintainers for xfce or maybe libglib2.0-0 on your distro.

I have encountered the same issues in xubuntu 20.04 on an nvidia 1660, however the last few betas have worked not caused crashes, no idea what changed. I am still encountering flickering of the window panel at seemingly random intervals during gameplay, possibly unrelated.

Disabling everything on this section of Settings > Interface seems to have helped:

The UI is still pretty glitchy tho, with white boxes appearing whenever a new pop-up shows/hides.

Well, it appears I was wrong about recent beta fixing this as I just managed to do again by re-enabling GPU accelerated rendering in settings. Shotgun debugging messing me up once more.

[yoyobuae]

So each new update has made this issue worse and worse.

Now the UI completely stops updating the graphics on the window. The UI does seem to change, and I can try clicking buttons completely blindly, but that's kinda not a good user experience. >.>

This is with all the options I showed above disabled.

I'm really out of options here. Steam is currently unusable for me...

[yoyobuae]

Can we get a way to return to the previous UI before all these updates? That one at least worked. And it also had stuff missing from current UI.

The -vgui launch param worked for a while, but not anymore. Now I still get the new non-working UI even with that launch parameter

[yoyobuae]

And now Steam never fully closes properly. I have to kill -9 the remaining stuck processes to fully get rid of it in order to restart it.

Hi! I have the exact same issue. It seems I can launch Steam with the new UI just fine, but launching any game has a high chance of crashing xfwm4.

If I try to restart it with the steam game open, xfwm4 crashes. If I close the steam game, then try to start it, it starts normally and I can see all the window decorations and panels again.

That's all dmesg says about it.
