Wallch/xorg abberation

[David Oxland]

Ubuntu 16.04 LTS
 Old Fresh Install
Using Wallch set to auto start and pic of the day
Ocassionally the display shows pic only as a portion with bottom portion grey-out as shown in attached.
Sometime the greyed out portion occupies 80% of the screen always from the bottom up.
Restart makes no difference
This occurance happens only occasionally, and I've caught a snapshot today
Usually wallch displays pic of the day correctly.
On boot, I do see some different activity discussing blocks occasionally b/w screen.(related?)
no other display aberrations appear in daily use.
