screenshot with a plain xfce4 desktop

screenshot2 with xfce4
Note that in the second picture there should be two different images: one for the iiyama X4071UHSU display and another one for the LVDS. What has happened is that parts of the LVDS displayed image have become visible on the HDMI monitor which is wrong (there is only one background image per monitor).

similar messages from nouveau - though without visible screen distortions

dmesg before crash
As it seems the same problems do also lead to more or less frequent crashes.
I have tested it back down to 4.8.0-rc2 and it showed that the problem does also exist with 4.8.0-rc2. Created attachment 126697 [details]
newer dmesg with 4.8-rc7+
The original page_not_present errors seem to have been resolved upstreams. Now there are other dmesgg in the log. The screen distortions seem to have improved but are not completely gone (linux commit 7d1e042314619115153a0f6f06e4552c09a50e13).
While there are only occasional screen distortions with xfce KDE5 plasma seems to fully break by these issues: see also https://bugs.kde.org/show_bug.cgi?id=368275. Just tell me if you should need more information; - tested with 4.8.0-rc7+. Created attachment 129678 [details]
current dmesg for 4.10.0-rc8+; no screen distortions - considered good
currently no such distortions with vanilla 4.10.0-rc8+; this has likely already been resolved with 4.9.0+.
not all screen distortions have gone; you can just not see any major distortions. Some screen content has just gotten warped on scrolling; another time I had some black spots above the font with thunderbird. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
