On X11, there are several ways KWin can invert screen colors: =
either by using
an OpenGL-based effect, or by adjusting the gamma ramp. While the former
approach works well on most hardware, we experience some issues with the la=
tter
approach on AMD hardware.

After adjusting the gamma ramp, the screen is filled with mostly white colo=
r.

Steps to reproduce:
* Open System Settings, go to Shortcuts, select KWin component under Global
Shortcuts tab, assign custom shortcut to "Invert Screen Colors";
* Press the shortcut.

(or just use xcalib -i)

Observed results:
The screen is filled with mostly white color.

Expected results:
Inverted screen.

Hardware: Radeon RX 580
Mesa: 19.0.3
Linux: 5.0.13
