Description of problem:
After installing the KDE spin of Fedora 25, my screen keeps flickering which I suppose must be due to some conflict with the graphic card. My workstation is using Optimus NVIDIA optimus where I have currently disabled the NVIDIA card and keep only the integrated one:
$ lspci -nn | grep VGA
00:02.0 VGA compatible controller : Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06)
As far as I know Wayland is now default with the release so any feedback on how to check for information from it or how to disable it are more than welcome.
Flicker is also visible on Live-user run, only requirement is the specific hardware.
Screen keeps flashing with varying frequency although refresh rate and all graphic settings are default.
Screen redrawing should be seamless.
I am ready to provide you with any configuration info you may require.
It seems that the most recent updates on Fedora fix this issue. No flicker appears anymore.
