Describe the bug

for some months, randomly
when the screen is locked
the dark breeze theme switches to a strange red theme. All is red instead of black.
I must close and open the KDE session to get again the dark breeze theme.

Strangely, we can't capture the red theme screen. If we do this the resulting picture is a one with a dark breeze theme !

I disabled clight to see if the problem is clight.

Expected behavior

The theme is not changed

During one day without clight, I never encountered the red tint problem.

I fear that with the KDE mega release and the following ones, clight became non-compliant with KDE/X11, at least gamma managing.

At least i must disable gamma managing.
