Test on latest virglrenderer-0.8.2-1.module+el8.2.0+5777+d9c2af8c.x86_64 Desktop UI also has chance to flash. The flash can be reproduced by using these GPUs: VGA compatible controller: NVIDIA Corporation GP106GL [Quadro P2000] VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Lexa XT [Radeon PRO WX 3100] VGA compatible controller: Intel Corporation Iris Pro Graphics 580 Hi Ademar, I suppose we should close this bug as won't fix now, since we already decide to drop virgl support? Thanks! BR/ Zhiyi (In reply to Guo, Zhiyi from comment #5) > Hi Ademar, > > I suppose we should close this bug as won't fix now, since we already > decide to drop virgl support?
