Gray box showing up when running coherence

I am running Windows 11 on PD18 in coherence mode. Periodically throughout the day, a large gray box will show up for about 10-30 seconds covering the left half my desktop. It looks and feels like parallels is trying to show a window, but nothing is shown. When I switch out of coherence, the box goes away. Is there any guidance as to what could be causing this? It seems to have started all of a sudden - without a change to my parallels configuration, installed version, or windows configuration.
 
For the record I have the same problem
Greetings GrahamB4,
Thank you for the information.
Our Development Team is working on a fix for this issue in future updates of Parallels Desktop.
We will get back to you as soon as we have an update.
Thank you for understanding.
Should you have any additional questions, let us know.
Have a wonderful week!
 
Here's another screenshot of the issue.

Same issue here with m1max OS 13.3
ps.
this login mail info is super annoying (it is "informing" me that i logged here in - this is hyper-bothering super-spam)..
 
Version 18.2.0 on M1 running Windows 11 Pro Arm64 edition. Giant gray rectangle shows up on the left of my screen randomly in coherence mode once every few hours and stays on the screen for about 15-30 seconds.
 
Same thing here, with latest MacOS and Parallels and Windows 11. I could make sure it's linked with the Windows VM, because when I pause it, the gray box remains. I've tried to disable much stuff (services and co) on the Windows side, to no avail.
