Description:

Ever since I started using 4.12.x series kernels I've experience general choppiness in gnome animations. This has been detailed in the forum discussion found here: https://bbs.archlinux.org/viewtopic.php?id=230149

Granted that gnome shell animations itself can be choppy in general (especially the overview), I have found that switching to an LTS kernel such as 4.9.51-lts has substantially improved the animation quality in gnome to an extent that I feel animations are acceptably smooth.

Other information:
I have not compiled the mainstream kernel from kernel.org. The kernels that I've tested with are kernels that I installed from arch linux repo.

Steps to reproduce:
1.) Install linux 4.12.13-1 or recent kernel (less than one month old)
2.) observe low fps fade-in/out animations when opening/closing gnome applications

Steps to fix:
1.) Install 4.9.51-lts linux kernel
2.) observe smooth transitions fade-in/out when opening/closing gnome applications
This task depends upon

4.12 is now end of life can you reproduce the issue on 4.13? https://www.kernel.org/doc/html/latest/admin-guide/reporting-bugs.html
Unless you can demonstrate it is a packaging or integration issue I doubt any action will be taken as a result of this bug report.

Yes it is reproduceable on the 4.13.2 kernel as well.

edit: Sorry, tested it on the zen kernel.

Maybe try to boot with "intel_iommu=igfx_off". intel_iommu is enabled by default now.

I cannot reproduce the issue with recent kernel.
Can we close the bug?
