Ubuntu 22.04.5 LTS
Kernel 6.8.0-45-generic

laptop Dell G3 17 - Dual boot with Windows

During the flcikering Sometimes even the user automatically gets logged
out. Files cannot be copied during the flickering: These files end up
being smaller in size.

It only happens when the mouse cursor is in the lower half of the
screen, but I do NOT believe it does NOT happen when the mouse is
moving.

The somewhat more severe flickering is accompanied by error "i915
0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun" in dmesg.

Flickering can't be recorded by Kazam, although the flickering was
visible at that moment.

The solution "intel_iommu=igfx_off" made the flickering completely
dissapear so I could use this kernel again :-)
