Bug description

On my Surface 3, when I lock my screen and wish to type in my password on the virtual keyboard, only the first character is accepted - further presses, even backspace or the button to hide the keyboard, do not get processed. So effectively, I can not unlock without attaching the keyboard.

Steps to reproduce

1. Install Mint 22.2
2. Install the https://github.com/linux-surface kernel via the APT repository
3. Reboot
4. Log in, then lock the screen
5. You now see the virtual keyboard - tap on it to attempt to input the password to unlock
6. Only the very first character is accepted, anything after, is entirely ignored

Expected behavior

I expected to be able to type in my password in order to unlock the screen.

Granted, touch screens under X11 are a little "odd", but when in the actual shell and apps, I can absolutely use the on-screen keyboard just fine. Only on the lock-screen does this behaviour happen.

Additional information

I have not had the chance to test this on any other devices unfortunately.

If none of us have a surface, we can't test this. We aren't installing some custom kernel for this either. The problem would be with cinnamon screensaver, not cinnamon.

Should I move the issue over to Cinnamon Screensaver, then?

Also, any idea how I could best debug this to provide better information?
