Thanks. Not getting the errors here, but trunk also stopped working in fullscreen (while 1.8 still runs). I'll try to figure out what's going on.

[Michael Zeilfelder]

OK, after testing this for an hour with different version... it turns out it works randomly here. Some starts work, some fail. No pattern. And I guess probably not the same bug here. edit: On further testing Irrlicht 1.8 also crashes randomly. Maybe something in X11 or NVidia driver or something like that has changed (changing resolutions was never such a good way to do fullscreen anyway, especially since the CRT screen days are over, so maybe graphic-stack devs no longer care so much).

[Michael Zeilfelder]

Do you maybe already use Wayland? I haven't given that a shot yet (last time it failed way before getting to testing Irrlicht, but that's been a while)

[Michael Zeilfelder]

OK, I'm trying some workaround for now in svn trunk r6648. Demo uses desktop resolution for full-screen which I hope will cause less troubles. And I realize now I probably could even have added that to 1.8... phew, sorry.

Can you test if that works on your system?

Closing now due to lack of feedback
