Hi all,

after last update to Plasma 5.21.0, screen started to flicker in X11 session. It does not flicker in login screen and in Wayland session. Is it known issue? Is it possible to revert upgrade to older Plasma version?

Thanks.

Problem solved. Adjusted display refresh rate from 60 Hz to 50 Hz and back to 60 Hz in System settings and flicker went away.

demm added the KDE SC & Applications Solved tags and removed the Deleted tag Feb 17, 2021.
