About scrolling due to caret moves.
Not sure if my suggestion in the other mail (7 Oct 15:12
SynNewScrollBarUpdate) helped?
If not, I can think of 2 causes.
1) The scrollbar change is not noted. If that is the case, I have no
idea (SynNewScrollBarUpdate does affect this)
2) SynEdit does not redraw all lines, but uses ScrollWindowEx to move
its canvas.
This is very common. I would not expect this to be an issue. Anyway you
can force it to redraw all lines (slower, and more battery if on a laptop)
Go to components\synedit\synedit.pp line 4653 inside procedure
TCustomSynEdit.ScrollAfterTopLineChanged.
the line is currently
if ScrollWindowEx(Handle, 0, LineHeight * Delta, @srect, @srect,
0, nil, SW_INVALIDATE)
replace it with
if false

but there is probably another change, because the NVDA is unable to
show me lines after I scrool with a down arrow to try to read the
contents. But that may be a NVDA problem.
