Playback interruptions changing color or info line

Cubase Pro 13.0.30. Windows 10.

I’ve had a second session now where playback is interrupted if I try to change a color of an event or change its volume on the info line. I had another session that behaved similarly but also had a very laggy GUI on just one track. It seems like it might be related to track versions. If I delete them, it seems to clear up.

Any similar experiences?
