Adjustment Layer Icons Disappearing

This is the third time I have had the contents of the Adjustments panel disappear on me.  The last two times I reset Preferences, but this time I thought to try restarting Photoshop, and that worked for me.  This has only happened with the Beta version, and this is after today's mini-update.  I am finding the beta version a wee bit flakey, with it hanging on me, but not closing before saving all open documents to the Recovered folder.

I have not been using Deactivate Native Canvas up till now, but I think I'll try it going forward as it has been fixing some unlikely sounding display issues on this forum.
