I can definitely apply patches onto that > version of KDE. It's difficult because I rewrote larger parts. I would not recommend it. If you have some space on the HDD you can re-partition the disk and do a dual boot on the same machine. In GRUB then your default boot entry could still be Fedora. > Maybe try with the 75Hz display first and see if the issue exists there too? > I think the issue will happen for anything above 60, but I could be wrong. Oh most likely it will happen. I assume it will just be less obvious to spot with a 15Hz difference. And since the internal perf tools of KWin seem not to be reliable just visual analysis could be needed. > Martin Floser was saying that if Painting blocks with vertical retrace is no > then refresh rate is ignored, so I figured the issue would happen on Intel > as well.

Alright, if you could test it out would be great just to limit the problem scope. -- You are receiving this mail because: You are watching all bug changes.
