--- Comment #6 from myndstr...@protonmail.ch --- > Display and windows too bright and "glowy" with large, bad-looking shadows > (white background) and glowing (on dark background) of windows I just tried it with my old graphics card instead of CPU-only and it's not too bright and "glowy" when using the graphics card. Strangely the graphics performance seems to be at least as bad as with CPU-only when using the nouveau driver and does have glitches where it shows green space across the screen which is why I removed it again. However, when using it I could change the HDMI Black Level from Low back to Normal. It could also be a bug in Debian but I only had this after upgrading from Debian9 to 10. Just wanted to add this to the bug report in case it's relevant to finding out what's causing it. -- You are receiving this mail because: You are watching all bug changes.
