Background: I have a MIPS/Loongson laptop. It may have bad RGB after a short uptime. It also may show some colorful mosaic.
This only happens with kernel built with gcc-9. I tried 5.2 ~ 5.5. It also only happens on desktop environment, not on console screen(control-alt-FN). does anybody meet the same problem on x86 platform? So that I can narrow the problem to gcc/kernel or MIPS unique.
