Laser engraving movement is jumping heavily when raster engraving grayscale (Bug Confirmed)

[pzq]

The gcode files seems to load faster in this beta versioin compared to 5.07.
But when i run the file its very jumpy. I attached the file i use. Acceleration is set to 3000.

With stable 5.07 version its a bit jerky but not that much.
I noted the jerky movement smooths out a little bit when the gcode stops scrolling on gcode view.
If im on override view the jumpiness in the beginning of file is not seen.

The movement is very jerky and super agressive compared to stable version

Movement stops totally and then continues while stable version reduces speed only with couple thousands of mm/min so when feed is 15000mm/min the stable version decelerates to maybe to 12000mm/min

The closed loop microstepping was set to 3200 but currently i reduced them to 800 to minimize the jerkiness in stable version. I didnt test the beta version with 800 microstepping.
