i will check - but i know i actually added yinvert checking code YEARS ago.
it's been there for a long time. you changes cause my entire display to have
every window yinverted which basically makes it impossible to debug and fix. :)
as this is a pretty severe change and it's not just on both my desktops (nvidia
drivers), users on #e started reporting it too yesterday so we went from almost
no issues to suddenly a bunch of systems affected. it's not a minor issue so
this kind of has "stay as is" until something better is done. :)
