I'm not using any special modes and/or sync ranges currently (although I tried 
that as well), and I removed the Monitor2 option, but nothing changed.

Nope, before posting here I tried switching through all of the available 
modes, also the ones that have multiple refresh rates available (eg. I tried 
800x600 at 60.3Hz and 59.9Hz, as well as a custom 50Hz defined by me). All of 
the different modes produce the same exact effect: correct vertical sync, 
wrong horizontal sync.

Thanks,
