Full screening an application makes things lag on other monitor.

[Latrolage]

When I have full screen unredirects enabled on one monitor, my other monitor gets very very laggy. They have different refresh rates.

Also, what actually does it mean by "unredirect"? I actually have no idea what this program does. I just wanted to try it out

sorry looks like the different refreshrate multimonitor issue was mentioned here #7 (comment).

But still what does it mean by unredirect? And is everything the same as default Kwin if i leave all compositor settings at default, or are there other changes?

Ok even without the "full-screen unredirects" option enabled, it still lags my other monitor with this compositor. It works fine on the default kwin compositor.

Logs from "Debug full-screen unredirection/direction scanout" doesn't seem to do much either. But this compositor makes my other monitor lag as long as something is fullscreen on one screen, and it worsens when "full screen unredirects" are enabled. (makes it basically 15-20fps or something)
