PGS can enlarge until 3000%.

PGS is fast for redrawing drawings (vector like) until 1300%.
When excessing this amount (like 1400% and so on) the redraw is becoming much and much slower. Especially when you want to edit the vectors.

Strange but not a big one.

My tests don't show a serious difference in speed. I'm sure a complex page will be slower editing, but if there is some unexpected, non-linear slowdown, I don't see it.

If you can supply a sample page that has this problem, I'll be glad to look at it. Just attach a file, and reopen the bug.

Maybe it is a Windows only one!

I just done it again, and I just went to 3000%. Only the vector drawing was not visible, so I use the scrollbars. Click, one vertical dimension higher on the white screen (only grid to be seen), and it took a while the redraw the grid lines.

So I closed this document and went straight for a new document (now no vector drawing on it), increased the zoom size at once to 3000%, and use the scrollbars to move around the page. Slow!

The same applies for Reshape tool redraw, when I changed something: slow.

Maybe it is only the redraw of the grid that slow things down when the zoom size is 1400% and higher.

I have the grid (Set Grid) at 0.1 mm.
PGS becomes slow (redrawing vector illustrations) when the grid is visible. So you have to zoom in, to see this behavior.
So Set Grid (0.1 mm) and zoom factor at 1430% (grid is showing) slows redraws, and at zoom factor below 1430% (like 1420) is fast(no grid to be seen).

So it is a grid and zoom depending behavior!

And it is not a complex page. A simple, small, circle on a empty page and zooming in, plus move it, does the trick.
