Public bug reported:
After the latest kernel update (5.4.0-45-generic) with the newest
version of this package, several visual issues occured:
- Cairo-Dock is grainy and semi-transparent (not caused by compositor)
- Text in several applications is grainy and blurred (i. e. in Vivaldi and
others)
- The GTK theme visual effects are laggy (Material Design -like Ripple on
button click)
- Dolphin Emulator visual and input lag in some games
Uninstalling Nvidia drivers and using Nouveau fixes it (althoug Nvidia
drivers performed better overall).
Using Ubuntu 20.04 LTS
nvidia-graphic-drivers 450.66-0ubuntu0.20.04.1
I ran apt full-upgrade, which upgraded my linux-image package to linux-
image-5.4.0-45-generic. After reboot, I expected it to work just as it
worked before. But the above described issues arised. I had to remove
nvidia drivers and use nouveau, but now my performance is degraded.
