Bug 376116

Please provide the output of:
qdbus org.kde.KWin /KWin supportInformation

Created attachment 103880 [details]
requested KWin support info

attached output of `qdbus org.kde.KWin /KWin supportInformation`

Created attachment 103883 [details]
kwin support info (60 fps)

sorry, the previous output was wrong (fell back to actual 60 Hz on the monitor after unplugging)

Created attachment 103884 [details]
kwin support info (120 fps)

Found info about MaxFPS and RefreshRate options in kwinrc, set both to 120 and it works.

support info also outputs the correct maxFpsInterval (8333333) and refreshRate (120). vBlankTime is still at 6000000, though.

> OpenGL platform interface: EGL

EGL is unsupported on X11 and we removed this gui setting some time ago. It could be an explanation why the auto-detection didn't work.

I don't know where this setting came from. But I can confirm the problem exists with an empty/fresh kwinrc. I've tried this before opening the bug here, obviously.
Showing 'GLX' then, still locked at 60.

Can you please attach the supportInformation for the glx case?

Added support info with untouched kwinrc
