Okay, digging deeper, there seems to be a bug at line 1325 of the latest sway’s cursor.c
I am able to reproduce a crash and coredump in sway any time I choose a beat subdivision timing within Bitwig-Studio. The selection process involves a mouse click to pull up the options mini-panel, and then holding the mouse button down while dragging to select the subdivision of a beat timing I desire ( triole, quintole, septole, etc…). Crash and coredump and abrupt end of login session every time.
from coredump analysis:
Core was generated by `sway’.
