Code:
direct rendering: Yes
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel Iris Xe Graphics
Attaching the video recording; might be platform-related after all.
This sounds like a minor issue, but in fact very annoying when you try to read a book.
Does anyone else experience the same? Is there a known fix?..
