Steps to reproduce the problem:
1. Open a crostini app (I tried with Gimp and Inkscape)
2. When it's fully loaded tab out
3. Now return to the program
4. Use text tool or try to open file
5. Program types some random letter infinitely until you press button like Tab or Shift

What is the expected behavior?

What went wrong?
I don't know why it's happening but apparently it's in all programs installed in crostini only.

Did this work before? N/A
