i915kms rendering slows down as soon as several additional GPU accelerated windows are mapped #184

Closed protamail closed 2 years ago

protamail commented 2 years ago

When using "autoscrolling" on Firefox everything is very smooth until couple more windows (presumably using GPU acceleration) are open. At which point scrolling becomes jerky. Once extra windows minimized, everything back to normal. This happens only when other windows are from programs like Firefox, Chromium, konsole, and does not happen with others like dolphin file manager.

DRM KMOD version Tried it on recent 5.10-lts and 5.7-stable branches

To Reproduce After reboot, open firefox with enabled "autoscroll" option. Try autoscrolling long page and observe hopefully smooth scrolling. Open couple more FF windows by selecting menu-> new window. Switch to original FF window and try autoscroll again.

Sorry, looks like it's KDE5 specific and happens on Linux as well. So not i915kms related.
