@sf67x,
Can you try disabling Hardware Acceleration in settings to see if this resolves the issue?

You’ll find this in Settings --> Additional Settings --> System --> Hardware Acceleration

Thank you for your reply! Indeed that solves the issue for now but not the underlying problem.

Edge browser somehow manages to default to the monitor’s refresh rate with hardware acceleration enabled even when Background Application Max Frame Rate (Nvidia Control Panel) is set to 30FPS.

Background Application Max Frame Rate is really useful when Alt-Tab-ing out of a video game as it limits the game at 30FPS while minimized saving both energy and heat by having the GPU no longer render the game at max frame rate since I am not actively playing the game.

I tried to get some attention to this issue in another post. The bug affects Youtube, overal Brave responsiveness and mouse gesture extensions. Both Edge and Chrome don’t suffer from this, so it’s not an underlying Chromium bug that could not be solved or anything.

My workaround for the time being obviously it not to disable hardware acceleration in Brave, as this would be detrimental for anything but bug reproduction. I also don’t like to disable the NVidia feature globally. So instead I set up the Brave profile in NVidia’s settings to disable the Background Application Max Frame Rate only for Brave. This seems to work, but practice will have to show if it is a viable long-term workaround.

Thank you for your suggestion! I followed your advice and set up a custom Nvidia profile for Brave and disabled the Background Application Max Frame Rate and it works just fine.
