Comment 61 for bug 1958191

I have been facing the "flickering occurs at some specific cursor positions and does not stop until the cursor moves" issue.
Now I have tried with `intel_iommu=off`, using the `Linux 5.15.0-39-generic #42-Ubuntu SMP Thu Jun 9 23:42:32 UTC 2022` kernel (latest 22.04 HWE).
Can no longer reproduce the flickering, and in general, graphics seem much more "stable", animations don't "stutter" like before etc.
