Can you expand on this a little bit?
I have (by chance TBH) fixed plymouth basically reading the CLUTs using
drmModeCrtcGetGamma() when plymouthd starts and writing them back using
drmModeCrtcSetGamma() before drmModeSetCrtc() is called when the reboot splash
has to be displayed.
But it's not clear to me why this is needed at all since in theory I'm writing
back the same CLUTs values read by drmModeCrtcGetGamma() but at the same time
if I do not do that, I have image corruption.
Any hint about this?
