Crashing after last update on mouseover

Hi there.
After last update yesterday, I'm experiencing a strange problem on beta.
When I launch it, if my mouse isn't over the game screen, it loads normally up to the char selection screen and I can use keyboard to navigate between my chars. However, if my mouse is over the game screen or I move it over the game screen, it INSTANTLY freezes. Even if i manage to ALT+TAB and log with any char.
I already tried to change to another mouse, play on only one screen, scan and repair game, update video card and mouse software, reinstall from scratch it but no success. No errors on logs too.
OBS: Live game works normally.

Here's a video of the problem: https://www.youtube.com/watch?v=vxQduWNmy0U
