Transparent backgrounds not showing checkerboxes

[ArctisStudio]

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.

Before the bug occurs

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.

@ArctisStudio not noticing the issue here with Photoshop version 25.5 on Windows 10, what are exact steps you taking to reproduce the issue, have you tried manually resetting your Photoshop preferences

Remember to backup your settings before doing the preference reset

Hi @Ged_Traynor 
Thanks for your answer. Unfortnulately I was never able to pinpoint what triggered this to happen. It seemed very random.
I manually reset my Photoshop preferences as you suggested. So far it seems to have solved the issue. Time will tell. I'll mark your answer as correct if the bug doesn't resurface for a while.

If you have the issue again, I'd be curious if changing the artboard background from transparent to white and then back to transparent again fixed things. I wonder if this is GPU/Native Canvas related.

Before resetting Photoshop's preferences I tried that. Sadly it made no difference.

@Ged_TraynorResetting preferences seems to have worked. Haven't had an issue since then. Cheers

@ArctisStudio glad you got it sorted 👍
