    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.

    Hello,
    Parallels Desktop 18.3.0 with the fix for the issue has just been released. Kindly update Parallels Desktop to 18.3.0 and check if it works for you.

    Same here.
    I'm using coherence mode 100% of the time.. Windows 11 is running in the background, and set to sleep when not in use (maybe it's related?).
    Every once in a while when I open a Windows program (even just the windows file explorer) I will also get this unclickable gray box window that covers about 33% of my screen (left side) for a few seconds, until it disappears by itself.

    Thank you, very hard to replicate this issue as it just randomly happens.

    not sure if it will pick it up or not, i may have done the report too slow, but i just hit the start button and the gray box came up.

    Thanks a lot, Jason!
    Unfortunately, there is no screenshots in the report, so we can't see what you observe and it's been taken a bit late.
    Would you reproduce it once again and collect it this way:
    - once the issue is reproduced, click the Parallels Desktop icon on the top Mac menubar > Help > Send technical data > click 'Attach screenshots and other files' > Send?

    I'm getting the same thing on a 2020 macbook pro w/intel proc. A gray box on the left side of the screen which appears randomly. Random meaning it can't be reproduced at will and is not allowing a screenshot. It seems to be happening to others...any ideas on when a fix will be available.

    I'm having the same issue - In Coherence all day long and this grey box randomly pops up at least 5 times a day. Sometimes without event interacting with Mac OS.

    I am getting the same issue with M2 MacBook Pro and Parallels running Windows 11. The gray box appears temporarily when opening a new Windows application

    Same here, waiting for a solution to this issue. Couldn't manage to get a screenshot so far, the appearance of the grey box being too much erratic.
