Mouse/Tablet issues when using Hej Stylus! in combination with Ai
Operating system: macOS 10.15.6
Graphics card: NVIDIA GeForce GT 750M 2 GB
Intel Iris Pro 1536 MB
Wacom Tablet, Intros Pro, or Cintiq 24 HD f.i.
Broken: Ai CS6+
Eilert from Hej Stylus! writing. Hej Stylus! is a tool that smoothes tablet output amongst other features.
Hej Stylus! pulls live tablet event data and re-infuses altered events back into the macOS event stream using:
Using any of Hej Stylus!' position smoothing algos creates cursor issues in Ai - on tablet use only. Mouse is not affected.
Using Tablet devices causes blender to 'use' both events - although Hej Stylus! is overwriting all tablet events.
We do wonder if you use any functions that force Ai to process information directly from a hardware source. We hope that you might shed some light on how you process incoming events from tablet devices so that we can find a workaround. Are you using 'mouseLocationOutsideOfEventStream' (or similar) to evaluate the screen position of the pointer? If so, under what conditions? Helping us to understand this process might help us finding a solution and providing a better Illustrator experience.
Exact steps for others to reproduce the error
1.) To test this issue goto: hejstylus.com and grab the latest version.
2.) Use a graphics tablet
3.) Use a smoothing algorithm (as seen in screen grab)
4.) Draw something with the tool f.i.
Today a similar issue was solved by the blender team for their application.
