-- Information about the crash:
- What I was doing when the application crashed:
I was using my tablet (Wacom MTE-450). I uninstalled the Wacom drivers, and am
using OpenTabletDriver instead. OpenTabletDriver is superior in many ways, imo.
OTD=OpenTabletDriver
- Unusual behavior I noticed:
The cursor was radpidly changing shapes. It almost looked, as if the cursor was
selecting stuff, and changing to a normal cursor rapidly or having the normal
cursor mode active st the same time.
There existed a bug in OTD, where it would click under specific condutions,
without the user actually clicking. Afaik I am still using a version, where
that bug is still there.
OTD has access to the raw tablet input devices (custum udev rules give tablets
input devices a chmod of 0666), and maps the tablet input to absolute onscreen
mouse coordinates.
The crash can be reproduced every time.
