User interface freezing in some applications.

[seb235]

Some applications, such as Bitwarden or SoftMaker Office, have a frozen GUI after switching from another running program. None of the program's functions work, X does not work, the context menu used to shut down the program does not work - the only option is to kill the process. The same applies to applications that ask to save your work when you exit. A window appears with a question, but it is empty with no options to choose from – you cannot save your work, so the only option is to kill the process.
