Frames rendered by the shell are of poor quality before screen is turned off and on
Fedora 32, GNOME 3.36, Wayland
Intel Corporation UHD Graphics 620 (512M prefetchable)
The surfaces painted by the shell are of very low quality. The shading is not smooth, and color differences are noticeable when drawn. This issue only manifests when I boot the system afresh. Once the screen goes to sleep (either on locking, or due to suspend), the issue goes away. The concentric circles drawn to focus on the shell prompts are also much more visible, and unlike what is seen during a normal run.
Steps to reproduce
- Boot the system.
- Observe the poor paint quality of frames.
- Lock/suspend the system.
- Everything is back to normal.
Poor quality of frames.
What did you expect to happen
Frames rendered before turning off the screen remain the same as after.
Relevant logs, screenshots, screencasts etc.
As a demonstration, here are the lock screen and shell "run command" dialog screenshots, but note that this problem is not limited to them, it happens for all frames rendered by the shell.
