Since one of the TW updates in December the display flickers immediately after logging into my Plasma session (not before) on my machine with an Intel Haswell Xeon. Switching off hardware acceleration (Shift-Alt-F12) gets me a stable picture, so something is wrong with that part of the graphics stack. In December, switching back to hardware acceleration after a while would work without the problem returning. After another update yesterday that didn't work anymore. I've tried to switch the renderer from OpenGL2.0 to OpenGL3.1 without success. Switching off tearing prevention seems to have resolved it (regardless of rendering backend), but I don't know what will happen after another round of reboot.
Did anyone experience the same or similar problems and have any hints on what else to check?

Hi, Sounds like Intel driver issue. Try to add xorg configuration and see if it helps. You can just create a file like 20-intel.conf on /etc/X11/xorg.conf.d Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" Option "TearFree" "true" Option "DRI" "3" EndSection And login again, or mightbe reboot.
