Bug description

Every once in a while my desktop will not permit text entries in any window. I can open new apps. I can open a new tab in a browser. I can switch between windows. In some cases clicking on a menu item will not result in the expected drop-down menu. I can open the Cinnamon/desktop menu system. I just can't type in any text field.

A command prompt shows a rectangle at the place you would normally type something but it seems frozen (i.e., no typing and no display change).

I have tried unplugging my USB keyboard and replugging them which does not result in an immediate fix. After a period of trying various things it suddenly starts working again (i.e., I can type in various fields).

The last time this occurred, I open the Cinnamon menu and clicked on System Settings. Immediately after doing that I was able to type in the Search field. As well, all other windows were type-able.

Steps to reproduce

No idea what causes this to happen. It may have something to do with switching between app windows.

Expected behavior

Typing should always be available as per normal.

Additional information

No response

No source file, test, or entry point is identified in the report. First reproduce the intermittent input failure on Linux Mint 21.3 with Cinnamon 6.0.4 and the reported NVIDIA hardware, then trace the affected window and text-input behavior; done means text entry and menu interactions work reliably across windows.
