Short description of error
use handle in the modal operator will draw nothing
using global handle will draw something for a second(in my test file, it did not draw anything, but print something for a second), then stop for no reason
please check the video
Exact steps for others to reproduce the error
run the test_file.blend
test_file.blend
@JulianEisel
Solved method: add
bpy.context.area.tag_redraw()in the modal function, helps refresh the drawingGood you found a workaround.
However it would still be good to check why this is not working as expected without the manual redraw tag
Not sure if this looks like #115549 ?
