Committed workaround for the crash, the error with multi-button sliding still needs to be fixed though.

Hans Goudey (HooglyBoogly) triaged this task as Low priority.Dec 22 2020, 10:39 PM
Hans Goudey (HooglyBoogly) changed the subtype of this task from "Report" to "Bug".

I think it's fair to call this a bug. Now that the crash is solved it's probably low priority though. One idea to solve this is to have some more persistent storage of button handle data on the panel level. The fact that it's reallocated on every redraw is what causes this bug.

Campbell has fixed the crash already so I think we can merge this report.
