Hey all. This is a plea for help. 
I posted https://bugs.launchpad.net/kicad/+bug/1806124 some time ago and haven’t been able to figure out exactly what steps cause this behavior.
that bug contains a video where I’ve shown the issue happening (unfortunately pressed keys aren’t included so you can’t see that part of it). It seems other folks aren’t able to reproduce and it’s sporadic for me. But when it happens, it’s annoying.
If anyone else seems this, even transiently, I’d love to know to confirm I’m not the only one. And if there is a for sure way to reproduce that would be even better.
