Description Lucia Mrenica 2022-01-27 18:14:54 UTC 
SUMMARY
Every time I open the log out screen my fps drops to exactly 30 (from stable 60) and stays there as long as the log out screen is shown.
This issue is visible both by eye and in the FPS meter effect.
My system is a fairly recent and should be plenty fast for a simple log out screen, plus, IIRC I didn't have this issue in the past.

I just noticed the same issue with Maui Index but not other Maui apps, so it must be something these two have in common.

How many screens do you have and what are their refresh rates?

Does this happen on X11?

Yep, looks like it.
