Every time I used private tab, it like hangs up a bit but i can still type and proceed the type after the hang for about 3 seconds and it does always when private window is open like affecting the whole brave. like each 30 seconds there will be a lag. This is a weird report or small issue. But just posting here maybe some people encountered it.
Maybe there is a gpu driver that is malfunctioning or not properly configured nor installed? I dont have any idea.
@nielle . I see from your screenshot you are using Wayland Windowing. As you have Nvidia graphics, you should be using Xorg windowing and not default Wayland.
Change that from your login screen, i.e. click your password field and look for cog icon bottom right of screen to change to Xorg (X11). See if that helps.
Ah. I now looked again at the screenshot and it lists "Radeon RX 580....
Fair cop, so it's not Nvidia.
It may still be worth trying Xorg instead of Wayland to test the response, but can go back to Wayland if no change and if Wayland is preferred.
