Activating the top bar or the system menu show the correct gamma/contrast of the screen (?) !
Hello GNOME Shell developers!
Today I discovered a very strange bug!
Normally when I look at my laptop screen all the colors look a little bit washed out and I thought this was due to either the screen of the laptop or the settings of the desktop. I took it for granted and I thought there was nothing I could do about it. But today I discovered that when I active the top menu or the system menu, the right contrast/gamma of the windows/desktop is/are shown!
To see what I mean, look at the following two screenshots (look especially to the gray background of the lists and cards at the bottom-right of the screen):
The first screenshot shows what I normally see (I adjusted this screenshot with GIMP because the screenshot tool that I used actually took the right colors) and the second screenshot shows what I see when I active the top bar or the system menu.
Can you see the difference? The contrast in the second screenshot is much higher and exactly how it should look like!
The funny thing is that the screenshot tool took the correct colors but when I normally look at the screen, the colors as in screenshot 1 are shown. Is this a screen driver issue?
Can anybody clarify the above problem/bug? Does anybody know what I can do about it (I would like to see the colors as shown in screenshot 2).
System: Fedora Silverblue 32
Desktop: GNOME 3.36.3
Display protocol: Wayland
Graphic card: Intel UHD Graphics 620 (Whiskey Lake) (rev 02)
Yours sincerely,
