Description:
I have poor graphics performance after suspend, using the latest kernel (5.5.2-arch1-1). Playing a 4K video in vlc with the "OpenGL video output" without hardware decoding, causes lags to the whole system (eg. moving windows, or just the cursor itself). The issue isn't restricted to vlc, though. WebGL performance is reduced as well. Kernel 5.4.15.arch1-1 is fine. After a reboot everything works well again. Logging out and logging in does *not* work, but for some reason if I log out, switch to a tty and kill the previous sessions with `loginctl kill-session <numbers>` it, also, works. Unfortunately, running a bisection isn't an option, as my internet connection is unstable. I'm filing this bug to see if others can reproduce. Additional info: * package version: 5.5.2-arch1-1 Steps to reproduce: 1. Set "OpenGL video output" as Output, and disable "Hardware-accelerated decoding" in vlc. 2. Suspend to RAM. 3. Start the system and play some 4K video. |
