After disabling compositing for fullscreen apss, this future restoring to enable. This problem on OpenGL 2 and OpenGL 3.1 render engines only. On Xrandr, this future work correct. Reproducible: Always Steps to Reproduce: 1. Start menu 2. System Settings 3. Dislay -> Effects -> Disable graphical effects for fullscreen applications
It's been forced down on intel chips because of https://bugs.kde.org/show_bug.cgi?id=252817#c194 *** This bug has been marked as a duplicate of bug 344319 ***
how then to be used if the hybrid graphics Intel / Nvidia? p.s.: for run 3D games, i use "optirun".
> how then to be used if the hybrid graphics Intel / Nvidia? disable compositing: you can create a window rule for that, so that when you run a game it automatically disables compositing. That's way better than the fullscreen unredirection.

Otherwise you'd have to optirun kwin (because that's the relevant GL context), but in that case you'd better just deactivate the intel chip (as the nvidia chip is in permanent use) But suspending the compositor is the better idea on performance concerns.
