FWIW, I also get this one (022554), along with two others (10ac08 and
6013d4).
The machine is an ASUS UX501V with an Intel HD Graphics 530 + NVIDIA GTX
960M (more details below). I'm running an up to date Debian 9.9 with a
4.19.28-2~bpo9+1 kernel (from stretch-backports). It is usually plugged
to an external screen though HDMI (32" AOC Q3277PQU at 2560×1440).

The last line is repeated hundreds of times.
It may be related, but am not sure: right after a boot, the graphics
(e.g. GNOME Shell animations) are fast and smooth, but after a while (I
think it's related to the machine going to sleep, and/or the screen
being locked), it seems to go to a fallback non-accelerated mode. It's
still usable, but even moving a simple terminal window is slow.
Strangely, even in this degraded mode, scrolling full-screen pages is
still smooth in Firefox, as is e.g. watching videos.
