Transparent backgrounds not showing checkerboxes
There is a bug where the checkerboxes indicating a transparent background on artboards suddenly is replaced by a gray background. Restarting Photoshop temporarily fixes this issue for me.
I noticed that the border of the Artboard also becomes gray instead of the normal blue.

After the bug occurs. Absolutely identical file, no changes made to file or preferences.

Is there a know cause for this issue that can be avoided?
Thanks a lot.
