This only happens with Eraser. Dragging over any line causes a noticeable lag/delay. Dragging over multiple lines in a row causes an even more significant delay.
Other than that, everything works fine. The machine is a Ryzen 9, with 128 GB RAM and a 16GB videocard.
Model complexity has no bearing. Even a simple flat CAD file, with no textures, has the same issue.
Is there something specific causing this, and how can I fix it?
