TeamViewer not starting correctly under Win 11 until PC rebooted

Colin_Southern

I have a client with a brand new PC running Win 11, and I've set her up with a TV account so that she can remotely administer her elderly father's PC.

A couple of times now (and I've seen this behaviour for myself) she's double-clicked the TV icon to start TV on her PC - TV appears as an entry on the task bar - but doesn't show on the main screen (as if it were minimised).

Hovering over the taskbar entry shows the expected thumbnail, but there's no way to get it to restore to normal/full screen. We've had a similar issue with the Settings app under Win 11 (known problem), but we managed to solve that. The only thing that solves the TV issue is restarting the PC. Any ideas anyone?

For all intents and purposes, it's acting as if TV is starting minimised, but with no way to restore it (I've tried clicking, right-clicking etc). Zilch.

Hello @Colin_Southern,

Welcome to the TeamViewer Community!

Did you try to open TeamViewer from the taskbar by right-clicking TeamViewer and selecting Show TeamViewer?

Let me know if this worked.

Customer is now away for our long weekend, but I'll be sure to follow up with this next week.

Hi folks,

The problem persisted with other (seemingly) random programs as well; so probably not something particularly relevant to TeamViewer. Having just said that, I am aware that at one point though, all the customer could see at her end was the taskbar thumbnail/preview whereas I could see the expected/normal program output whilst viewing her screen via TeamViewer ... something that I didn't previously think was possible.

I posted for help on the Microsoft Community Forums (https://answers.microsoft.com/en-us/windows/forum/windows_11-performance/intermittant-issue-with-various-apps-appearing-to/98c51788-4644-4b40-96c4-a2aeac767bee) and received a reply from a chap who's had previous success holding down the shift key whilst right-clicking on the taskbar entry ... then selecting "move" and using arrow keys to position the window. As another user found this helpful after experiencing what appeared to be an identical issue, it does seem to suggest that the issue is "merely" Windows 11 glitching and trying to display the program's output outside of what the monitor can display (as opposed to something more sinister) (but to be honest, we're still pretty much at the "who the heck knows phase).

Interestingly, I also disabled taskbar previews ... and it's looking like this may have had an effect too (bit early to tell, but it's been 24 hours and no glitches so far).

Hope this helps someone.
