Hello.
Using Nvidia binary driver 465.27 and disabled nouveau driver and default settings in nvidia control panel and bright panel.
The problem is that white color is very high how if OS is using an color settings.
Is how if all screen is using an color adjust that does white color to be an high bright level.
That not is changed using nvidia control panel or the bright panel.
see the screenshots with naming 21.04 how the window title font is extremely white comparing with 20.04.3.
bug in nvidia driver or OS using an wrong icc and or an internal “color correction” breaking the white color ?
Tested 20.04.3 with nouveau because not nvidia drives was released for 20.04.3 in moment , but in 21.04 using nouveau also happen that problem.
20.04.3 happen that problem with white color, but much less than 21.04.
