Revert "Merge branch 'pr/711'" (...)

Temporary revert to the old debounce behavior. It's a bit bad and drives
up CPU usage, but mostly shows correct info in the GUI. This will be
improved shortly.

This reverts commit 51443308074456ef8f6ca62b29de0bc7ed3aad85, reversing
changes made to c34f3defe1aa1fe28aca1d5e69b712d4d857da49.
