For how to run the latest Guake in your computer, please refer to Install from source.

Describe the bug

I've been using Guake for a long time and I could always toggle Guake using hotkey for Ubuntu. But recently when some applications are active like Files and Firefox, the Guake hotkey does not work anymore. For some other applications it is working, like Google Chrome, VSCode.

Expected behavior

That I could toggle Guake when any application is active.

Actual behavior

What you actually get.

To Reproduce

Please run $ guake --support, and paste the results here. Don't put backticks (`) around it! The output already contains Markdown formatting. And make sure you run the command OUTSIDE the Guake.
