my system:
Lenovo Thinkbook 15 Gen4 (IAP)
12th Gen Intel® Core™ i7-1255U × 12
Mesa Intel® Graphics (ADL GT2)
Ubuntu 22.04.3 LTS
My Problem:
After the last software updates a few weeks ago, i now have a weird graphics glitch wich renders my device partially unusable.
The bug only appears when i switch something to fullscreen. Be it videos in the browser, pictures with image viewer, videos with VLC, or any other window wich allows being set to fullscreen via the F11 key.
Also maybe worth to note: windows runs fine on this machine. So no hw/firmware issue.
I would be super thankful if someone of you good people over here could guide me on how to solve this problem.
Attached below are example pictures of a fullscreen YT-video with and without the glitch and also a screenshot of the "additional drivers" window.
This might also help?
