This problem is still persisting even after rolling back graphics drivers and some other things. I have no clue what is causing it, but I makes Wings virtually unusable for me on anything with a certain polycount or a bunch of objects. Would really love to know what this could be even caused by.
On a project with like 5000 or so quads selecting a vert literally takes almost a minute. :/
