Same underlying reason as for the 600ms keyboard pauses I saw.

One #winehq person claims that ATI and NV drivers track monitor
state and cache resolution information, which is what wine queries
on startup.

It feels like it is being done twice.

I'm taking a look in the wine code. I hope it can be resolved. I
guess it's this call to XRRSizes():

Maybe make_modes() is also involved:
