KDE compositing crashes on latest NVIDIA drivers (version 384.90+). Just run any fullscreen game, Steam or VirtualBox in fullscreen mode and it will crash:
Oct 28 22:20:22 local kwin_x11[1200]: kwin_core: OpenGL 2 compositing setup failed
Oct 28 22:20:23 local kwin_x11[1200]: kwin_core: Failed to initialize compositing, compositing disabled
Oct 28 22:20:42 local kwin_x11[1200]: kwin_core: OpenGL 2 compositing setup failed

Fedora 26 with KDE Plasma 5 DE.
Linux kernel version: 4.13.8.
KWin version: 5.10.5.
I am facing the same issues, but it seems Nvidia has 0 interest in getting that fixed ! No reply to each of this threads :(. It’s a shame, but my next gpu will be 100% a AMD one utilizing open source drivers.
This bug still very much happens on KDE 5.11.5 and nvidia 384.111. It almost happens completely randomly and I have to fully restart the system. I can’t believe Nvidia won’t fix this, this is their problem.
