SUMMARY

This has happened 3 times recently,  when I open a new application, the window or background around it start to go into rapid flickering. I once has my 2nd monitor entire desktop go into a flickering, it will remain like this until you click on the desktop or move the window.

I don't know what is causing this. Funny enough when I open "Info Center" it just happened now. OK it seems on openSUSE TW I can reproduce this with the following steps.

1. Open a few windows
1. Press ALT+SPACE, type, "info" to open Info Center.

Flickering starts immediately!

I'm wondering if this has anything to do with the latest NVidia RTX 3080 driver?

I rebooted the system and the steps outlined below no longer reproduce the flickering behaviour.
