bCNC is very slow on Rpi4 #1917

jdelahayes commented 3 days ago

I've been working with bCNC on an Rpi3 for a while without any problems. I would like to install bCNC on a Rpi4. The last version of raspberrypi OS is a Debian 12.8 with Python 3.11.2 and I reinstalled bCNC without problem from the git repository.

But it is very slow, the tabs are displayed gradually and when you load a gcode it becomes unusable. Has anyone encountered the same kind of problem on a recent installation of bCNC on Rpi4?

After testing and researching, the slowness is probably due to using xWayland since Debain Bookworm.

Similar problem found on Thonny project: https://github.com/thonny/thonny/issues/3036#issuecomment-1872394923

I downgrade to Debian bullseye. bCNC UI performance is as usual.
