It should be checked at different V/div settigs, comparing normal and hires mode at each V/div.

Not every possible V/div setting, but not only at 1mV/div either.

Maybe 1mV (already done), 100mV and 1V.

Also try changing the horizontal timebase, see if Hires works better/worse at different settings. Try and  find anything interesting.

--- End quote ---

The mathematics behind Hires mode are very simple, it's hard to imagine why it wouldn't work.

Then again, there must be a reason why it wasn't in there on initial release.
Anding:
single-shot mode, force trigger


Anding:
10mV / division


Anding:
100mv / division


Anding:
1V / division
