Same issue as discussed in this thread but with PyCharm:
Simply put, when I change focus to another app (a browser, Slack, GitHub Desktop, etc.) and return focus to PyCharm, I can no longer type. Changing focus between consoles/files within PyCharm fixes the issue but it's pretty annoying.
I'm new to MacOS (Catalina) so I'm not sure what 'restart i3 in place' means and if it's still relevant in this version of MacOS. I tried the keyboard shortcut shift+option+r and it didn't do anything. I'm running the latest version of PyCharm - 2019.3.4
Any help will be appreciated.
