Openboard causing very high cpu usage when using eraser

Message par mendeli » 03 Mars 2021, 13:49

I am using Openboard on a Lenovo Yoga 920 with Ubuntu 20.04 and I have noticed that when I use the eraser with my Lenovo active pen 2, the cpu usage peaks up to 700%. Sometimes Openboard hangs and I have to restart the program.

- I tried using the pen with xournapp and did not have cpu issues, therefore I don't think this is a hardware problem.
- I was using Openboard on the same machine last year with Ubuntu 18.04 and had never noticed these issues. I had very few problems during last semester.

I really like using Openboard for my classes, but these constant hangs are making it very difficult. Can anyone please help?
