The general flickering of the entire screen makes me think this is an issue with your graphics driver. Please attach your system information to your bug report (Help > Save System Info).

@Jeroen-Bakker I'm not sure if this is an issue with our graphics drivers or if this is indeed a bug in Blender.

I think that it Blender 2.92 issue because the Blender 2.91 doesn't have this issue on my machine. I now updated Mesa from 20.2.3 to 20.3.0 and the issue also observe but don't on v2.91

I can also reproduce on Linux with RX550. I will bisect and check if this points to same commit as #83094, I haven't got build env on Linux yet though.

Also managed to reproduce on windows - Start with General template, change 3D viewport to sequencer

I can reproduce with Blender 3.2.1 on my Dell Precision M6600 / Nvidia Quadro 3000M/PCIe/SSE2.

I have no general screen flickering, but these Channel artifacts are impacted by resizing the Blender main window. No other applications on this system are impacted.
