There is still a problem with the display of channels A and B (but no crash). Both channels are grounded, the problem happens with the short as well as with the long buffer:

• in AUTO and SCAN modes, I have huge offsets on A (e.g. 6 V on a 2V/div scale)
• In SCAN, short buffer, sometimes it refreshes the screen several times per second with a 1s time base (!) and trigs on a square impuls of 6V (2V/div) and 1div long (synchron on both channels) - with grounded inputs…

I’m now seeing this behavior as well. Didn’t happen in the previous builds.
Tried running the calibration procedure and that seems to go well, with only minor offsets detected, so something’s wrong in the other part of the code.

At least we are now seeing the same thing
Predictable/reproducible behavior is a great step forward

…now all it needs is a bit more love&care to squash some of those nasty bugs.

EDIT: Seems to be a question of the offsets being completely messed up.
Inputted a 2 volt square from the signal generator into chA and the signal itself is perfect in all scales…
