Full screen video on Plex for Windows in weird windowed mode when Windows 10 Tablet mode enabled

Server Version#: Not applicable
Player Version#: latest Plex for Windows 1.63.3.3523-1eff9563

I am using Plex for Windows on Windows 10 22H2. I am one of these people who appreciates Live Tiles (unfortunately there aren’t many apps supporting these anymore) and I am running Windows 10 on my HTPC in Tablet mode so that I return to the full screen Start menu whenever I close an app.

For quite a while now Plex for Windows seems to have had issues with Tablet mode on Windows 10. Indeed, when I run video on Plex for Windows full screen, Plex for Windows resorts to some sort of windowed mode taking up only part of my TV screen. When I turn off Table mode on Windows 10, Plex for Windows handles full screen video as one would expect.

This issue can be consistently reproduced.

This issue does not occur on Plex HTPC. Unfortunately, however, Plex HTPC is unusable for me since mouse scrolling using my Microsoft all-in-one keyboard does not seem to be properly supported on Plex HTPC, while it is on Plex for Windows.

A fix would be greatly appreciated.

Plex Media Player has been deprecated for years now.
Are you sure you are not talking about “Plex for Windows”?

Please give the actual version number.

You’re right - Plex for Windows. Apologies for the confusion - I occasionally still get confused with the naming changes (have been happily using the UWP app until that got canned, then PMP until that was no longer available,…). I corrected my initial post.

Current version I’m using is 1.63.3.3523-1eff9563, but have experienced the issue for several months on previous versions as well. Unfortunately I don’t remember what version I upgraded to when I first experienced the issue.

Thanks!

Go to
Settings - Plex for Windows - Playback device
and play with “Playback Quality” and “Hardware decoding”.
Maybe there is a way to change it.
On low-end hardware (i.e. tablet) I’d try the ANGLE renderers.

Thank you for your suggestions - I appreciate it.
I tried all combinations of playback quality + enabling/disabling hardware decoding - but they all gave the same result: some kind of windowed-weirdness when going full screen on Windows 10 in Tablet mode, and working just fine with Tablet mode off (which serves as my workaround).
