Hi there,

I am recalculating the slice views to see a line in two parallel and one perpendicular view. In the perpendicular view, there is a weird bug that the slice intersections are broken or refracted (see the screenshot below). After I hover with the mouse above the (yellow) slice view, the lines straighten again.

Can someone explain the bug? And if I can somehow get rid of it? The weird thing is, that it happens only in the perpendicular (yellow) slice view.

Thank you!
