Hi, I've been using MATLAB for a project and generated some figures, slept my laptop and then went to lectures the next day. When I opened my laptop I was met with these two figures. I've restarted my computer, used task manager to force quit, and use all variations of close all and close all force. The windows are still there. I cant interact with them, move them, or in any way effect them. They always appear in front of other windows.
They are also present on the lock screen.

Hi @Siddhartha,
You can try deleting all figures unconditionally by using these statements:
set(groot,'ShowHiddenHandles','on')
c = get(groot,'Children');
delete(c)
If the issue still persists, you can try performing a clean install of MATLAB or kindly reach out to MathWorks Support for better resolving this issue:

Sounds like some kind of Windows sleep quirk. They won't remain after rebooting the computer. I don't know what went wrong in the first place but rebooting will fix it. It's not like that data is permanently burned into your display RAM memory. Rebooting will clear it.
