https://bugzilla.kernel.org/show_bug.cgi?id=205915 --- Comment #11 from Manuel Ullmann (labre@xxxxxxxxx) --- Reverting 1ea8751bd28d1ec2b36a56ec6bc1ac28903d09b4 on HEAD, currently 5.5-rc7+, seems to fix it. The revert should probably be limited to the 2 hunks in the clock manager files to preserve the underflow avoidance: - if (update_dppclk) + // always update dtos unless clock is lowered and not safe to lower + if (new_clocks->dppclk_khz >= dc->current_state->bw_ctx.bw.dcn.clk.dppclk_khz) For the sake of comleteness: Steps to reproduce: 1. Suspend with Navi and activated display core. 2. Resume. 3. Start glxgears. Actual results: Animation flickers. This happens on any OpenGL accelerated task, like Firefox with hardware acceleration or similar. Expected results: Flicker-free rendering. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
