I’ll tag @Mattches on it in case he can respond more later and maybe get it to devs attention. However, I’m going to assume it’s mainly Nvidia you need to contact. Earlier this year on that Github, person responded with info below:
I’ll also direct you to a similar topic that was created, which might have some helpful info for you:
Of course, part of what Mattches and all found out was that disabling hardware acceleration resolved the issue, but it’s not necessarily an ideal solution. So as link says above, you can also set Brave as an exception.
And with what I’m seeing in different places, it might be that people need to contact NVIDIA about it directly. This is especially the case since it’s said not to happen with Chrome, Edge, or Firefox but supposedly does happen with Vivaldi and Brave. It just means they have exceptions or whatever set to their driver.
