[PATCH xf86-video-amdgpu] Do not push the CM_GAMMA_LUT property values in drmmode_crtc_cm_init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michel Dänzer <michel.daenzer@xxxxxxx>

The crtc->gamma_lut values aren't initialized yet at this point, and
the property values are pushed again from drmmode_setup_colormap
anyway.

Fixes intermittent flicker due to random gamma LUT values during server
startup.
