Screen corruption when screen returns to app

Roon App for 1.8 running on a Google Pixel 4, Android version 11.

Has anyone else noticed (or is this a known problem)… what looks like big corruption to text fonts etc after switching away from the Roon app and then back to it? Once this happens it is fairly permanent… all further screen redraws have similar corruption of resources, fonts etc.
Only way to fix it is to “force stop” the app in settings and then relaunch it.

This does not happen on my old Samsung Galaxy Tab S2 running Android 7.

I’ve seen this on Pixel 6 Pro a few times.
