Playing a video with "blank screen item" enable causes lockup

[c3aJeff]

In Zoom, OnlyM doesn't show up in the screen share menu unless something is playing (or blank screen item is selected) however if blank screen item is currently running and I hit play on a different video, OnlyM completely locks up (the only way out is: task manager / kill process) however, I made my own jpg "blank item" and that works fine.

Hey. I would advice you to use the "Permanent backdrop" option - this works very well!

Using Permanent Backdrop does work well - however, I also noticed that the lockup problem is resolved by switching from "Media Foundation" to "Ffmpeg" in Videos & Audio.

As a side note, I am on the Windows 11 21H2 beta (22000.168) and with the 160 update, MOnly would not work using Media Foundation. By unchecking JW Library Mode, selecting Permanent Backdrop and switching to Ffmpeg, it's working again.

@c3aJeff Which version of OnlyM are you using please? From v2 I am hoping that a bug in MediaFoundation will have been fixed - a bug that can cause video rendering issues on a secondary monitor.

I am using 2.0.0.10 Also, note that it was not working on the 2nd monitor - so I moved it to my main display and it had the same, repeatable problem - MOnly locks up (the only way to close it, is to kill it with Task Manager) - The behavior is odd; when using Media Foundation - MOnly will load images and pdfs ok but if I switch too quickly it locks up. It will ALWAYS lock up if I click on any Mp4 (video) when I click once, it just flashes but won't play and does not indicate that it is playing anything... If I click again, then it looks like it's starting to play but locks up. Changing to the permanent backdrop AND Ffmpeg, everything is working - I can reliably switch from an image and fade into a video without locking up, or just play any mp4 without issue. Switching back to Media Foundation results in the same issues as before.
