This probably seems somewhat reaching since CrossOver isn't Wine, but well, it's built on Wine, so I thought I might get some help anyway.
I'm running WoW through Innerspace, which causes some weird problems.
With Innerspace loaded together with WoW it'll act as alt + shift is being held down.
Innerspace has an alias binded to alt + shift + t which will make WoW go into "tiny mode". But in my case, if I just type the letter "t" it'll go into tiny mode.
I also have some problems with the charset or something like that, this is what my console look like:

Shouldn't look like that

I've tried to install Courier, Tahoma and Verdana, but that didn't solve anything.
I don't know if anyone else here has experienced anything like this with Wine and Innerspace/WoW, or if anyone here even uses Innerspace. But I thought it was worth a shot.
