But not repro with Version: 6.4.0.0.alpha0+ (x64)

So likely fixed somewhere in master toward 6.4; needs reverse-bibisecting to find what needs backporting.

@Roman, @Buovjaga, any chance you could reverse-bisect it ?

Comment 11 Buovjaga 2020-08-28 12:20:45 UTC 
As Skia with Vulkan will replace OpenGL UI rendering on all platforms, it does not make sense to keep OpenGL UI reports open.
