So, I did a lot of work in order to eliminate future problems like this.

• I set up basic integration testing for aw-qt: https://github.com/ActivityWatch/aw-qt/pull/14
• Managed to replicate it: https://travis-ci.org/ActivityWatch/aw-qt/jobs/23893596
• Implemented a working fix: https://github.com/ActivityWatch/aw-qt/pull/15

So, fixed! Thanks for being our macOS bug catcher @theguybieber 😉

Perhaps someone on macOS could test if this workaround is still needed?
