Lively application window border artifact

[anfokaboom]

Describe the bug
On some occasions, following exiting a fullscreen instance of (so far) OnlyOffice, Lively leaves a window border as shown in the screenshot. Exiting Lively removes the artifact, and when Lively.exe is relaunched, the border is gone.

To Reproduce
Steps to reproduce the behavior:

1. Run Lively which loads expected wallpaper
2. Open OnlyOffice document in full screen
3. Close OnlyOffice document
4. Sometimes see app border artifact

Expected behavior
No window border artifacts should be present on the monitor

Screenshots/Video
If applicable, add screenshots/video to help explain your problem.

Desktop (please complete the following information):

• OS: Windows 11 Pro 23H2
• Which wallpaper was running at the time if any: Custom mp4 at 2560 x 1080

Additional context
At all other times Lively and the wallpaper appears to run fine. I only noticed the issue occur after I closed a fullscreen OnlyOffice document

The same thing happens to me as to these 2 users, when starting Windows 11 the video appears with borders, to remove it I must end the process and reopen Lively so that it appears correctly and without those annoying borders, I mention that this happened since the most recent update, before the update it worked perfectly

Try creating a mpv.conf file

border=no

and save it in the following folder:

I'll try it and comment on the results! Thanks for the reply!

Edit: The solution works perfectly, thank you very much for the support!
