Are you using a macro or something to fill in sheet number? AFAIK there is no logic in TD to calculate a sheet number or total sheets.

It isn't a command. It is a property of the section's base view.

The model is from https://forum.freecad.org/viewtopic.php?t=86528 , even not does not matter. It also does not matter how big the drawing is, it occurs randomly and an only get repaired, when you restart FreeCAD. Yes, I've seen this also. The zoom-at-cursor setting seems to get ignored sometimes.

Yes, please. It would be great to make the template fields "expression aware".

As others have said, without an actual file we are guessing, but the missing lines may be due to the issues discussed here: viewtopic.php?t=46024

TechDraw seems not to use graphic acceleration. On larger drawings, it is absolute needed (have here ~ 1FpS - 4FpS), reaction time ~1s - 2s of selection. Do you have a sample file to use for benchmarking this? I'd be more inclined to blame scene indexing here, rather than graphics accel, but would ...

some progress...
