I don't... but it appears straightforward to do. See patch. Works fine
for me.
Hello Martin,
It seems to work fine on screen but...
+ //expose(0, 0, workarea().workWidth(), workarea().workHeight());
+ expose(0, vi.y1, workarea().workWidth(), vi.y2 - vi.y1);
I get negative y-position when I page down with your patch:
expose 671x563+0+-80
expose 671x563+0+-80
expose 671x563+0+-80
expose 671x527+0+-68
expose 671x527+0+-67
When I scroll to some other place I have:
671x740+0+-210
Which should be
671x740+0+0
shouldn't it?
Ouch, this looks creepy. Like painting on air...
Try the attached new patch. It seems we were still painting too much,
and even with this new patch, no visible loss of... anything.
The numbers seem more correct now. But I still see the same problems
with Ctrl+n and Ctrl+end. There are a few weird things though:
When I select with shift+down in a standard paragraph, I get the following:
expose 671x156+0+78
expose 671x156+0+78
expose 671x156+0+78
expose 671x156+0+78
expose 671x533+0+0
expose 671x533+0+0
expose 671x533+0+0
expose 671x533+0+0
Notice the jump from 156 to 533? But I don't see any drawing problem on
screen.
Abdel.
Weird.
