--- Comment #1 from jackyguo18@hotmail.com --- Updated to winehq-staging (version 7.2) and the bug still persists, though the titlebar is now rendered correctly. Ignore the description I wrote in the first comment, it should say:
When closing the emulator (not the entire app), the TASInput window remains and freezes up.
