THE PROBLEM PERSIST!!!
When hardware acceleration is activated, there are rendering problems in the browser itself!
The problem manifest as some form of pixelation, blur or werd shaping lines (not sure… maybe a mix between those) around fonts, shadows and color gradients.
It happens randomnly, some times over the browser menus, sometimes on images, sometimes over buttons.
In videos, when it happens, its mostly when the video is paused and it covers almost all the video player area.
After moving the mouse over various affected areas, most of the times, the problem disappear (gets fixed). In videos, it generally fix itself when resuming the video.
Disabling hardware acceleration fix the problem… but the CPU load doubles … sometime even a bit more, wich in low spec PCs, got the videos to show stuttering or simple freezing the video image for a couple of seconds before resuming.
With hardware acceleration disabled in a intel i5 6500 (old mid-spec pc, but still pretty decent) the cpu consumption of brave browser got near the 40%… totally unacceptable, even more if you guys consider the really good 3% to 12% max of cpu load with hardware acceleration.
