As you read, I upgraded Gnome Desktop in Manjaro Linux,
Gnome Animation is not working and lagging.
Can someone tell me about this problem? Thank you.
You should ask on a Manjaro user support forum.
One thing that can cause animations to get disabled is using software rendering. Make sure your graphics card drivers are still working. If you are using proprietary drivers, maybe a kernel update caused the kernel modules of the driver to not work anymore.
I think I found a problem.
Thank you everyone.
