Created attachment 186919 [details] Video On a monitor with 160 Hz, the screen flickers when I click on something or move the mouse across the screen. If you turn on 60,120,144Hz, the flickering disappears. The video doesn't convey how much flicker it is (it looks worse in real life).

This may be a driver issue. Can you give us the following information? Information about your monitor with kscreen-doctor -o Also, attach the output of drm_info Thanks
Created attachment 187013 [details] drm_info.txt I agree, maybe it's the video driver. I searched the forums and they say that there is no such problem in Gnome. I installed Gnome for fun, and there was no flickering in a few minutes of using it. I am attaching information from drm_info to a text file, as there is a lot of it. I really ask you to solve the flickering problem, because it prevents me from fully using my new monitor. The lower right part of the screen is flickering and I do not know what to do about it.

The second part of the message: Can this harm and damage the monitor itself?
Completing it. The problem happens everywhere, but I don't understand the principles by which it appears. Sometimes everything can be fine for a few minutes, Sometimes it appears. But it is found everywhere. Unfortunately, some screen twitches and blinks appear on their own, and some when I move the mouse. For example, when I was recording a video from the game, I didn't touch anything at all. I turn on my computer and go about my business, and after a few minutes, the flickering starts in the lower right corner. I also attach a video as the monitor flickers in the game. The most interesting thing is that as soon as I want to record this bug for a bug report on my phone on video, it disappears for a few minutes.

Thanks for the details, that's useful. The kwin developers will look into this from here.
