Dear regarded mapping community (inb4 reflex sniggers),

When I right click in the 3D view window of Radiant, in the x-y plane the view rotates like crazy. Oddly it's just fine in the other two planes.

I have tried 2x 100% fresh installs to check I didn't mess something up.

Looks like I'm not alone, either.

here someone posted a fix but the link is dead and the page is archived.
here nobody found a fix

Will have to use arrow keys for now :(

Does anyone have any ideas to fix this?
