From f5b5ad2c59b4e132dc1daa24077ea80c1d18a016 Mon Sep 17 00:00:00 2001 From: Mikhail Vanyulin <mikhail.vanyulin@rtsoft.de> Date: Wed, 24 Apr 2024 17:22:01 +0200 Subject: [PATCH] weston-init: fix display flickering Refer to https://secogroup.atlassian.net/browse/YT-85 for full discussion on this topic. For some unknown reason, when the transparency part of "background-color" parameter in weston.ini is lower than FF, display (both LVDS and HDMI) starts to constantly blink if some object/sprite is moving on display. Herewith this issue cannot be seen if application is launched in full screen mode (e.g if seco-show-demo is running). But if seco-show-demo is stopped, the problem immediately appears when a mouse cursor or "weston-flower" are moved. As digging into weston internals to understand what is going on will require reasonable efforts, we simply changed background-color to 0xFF000000, which also produces a black background, but which does not cause the blinking issue to appear.
