Key frames captured from a Haswell machine, showing artifacts on a Qt menu.
Added : same issue can be observed in two more machines with different
hardware.
One is a samsung ultra-book.
CPU : Haswell i3-4020Y (HD Graphics 4200)
distribution : Arch Linux, with almost up-to-date packages
kernel : 4.11.9-1
xorg-server : 1.19.3-2 (use modesetting driver instead of intel DDX)
mesa : 17.1.5-1
DE : LXQt 0.11.0
Another is a HP ultra-book.
CPU : Ivy Bridge i3-3227U (HD Graphics 4000)
distribution : Arch Linux, with almost up-to-date packages
kernel : 4.11.9-1
xorg-server : 1.19.3-2 (use modesetting driver instead of intel DDX)
mesa : 17.1.5-1
DE : Mate 1.18.x
On both machine, The glitches & artifacts vanish very quickly, it's hard to
see, but they do exist. You may use a camera, and inspect the recording frame
by frame. See the attachment.</pre>
