From a923bedfd91d39977dbf95f296cf9b68439490f2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michel=20D=C3=A4nzer?= Date: Fri, 31 Aug 2018 12:44:37 +0200 Subject: [PATCH] Do not push the CM_GAMMA_LUT property values in drmmode_crtc_cm_init 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.
