Yes, that patch would indeed fix it in my case.

I was pretty sure i took standard VESA modes and the fact that Windows Generic
Monitor (no overrides or "hacks" there) values also using the same timings
tells
me that they re rather "normal" modes.

i'm going to take your fix and live with it because i prefer when all my screen
modes remain exactly the same between OS switches.

But for curiosity reasons. Do you have a suggestion for mode sources with
higher
vblank pauses which are still considered "standard" and not totaly uniq and
custom? Or might it be possible my 85 Hz value simply has this 450 as standard.

Anyway, thanks for your help.
