Is it visible in the exported image? Could you provide a file so I can debug?
i’ve managed to catch it again, the way i reproduced it is the following:
made a file, doesn’t matter the size.
put on vector drawing mode
drew a couple of straight lines
moved it to my secondary monitor specifically, which is 1920x1080
it only happens inside the viewport as far as i’ve seen, these offset places seem to be of a diagonal pattern i guess??
