Description Maciej Stachowiak 2006-02-11 21:45:58 PST

Filters appear to apply more and more times on each repaint. This is visible in the effect of the filter, and the paint gets slower and slower each time.

Steps to reproduce:

1) Load LayoutTests/svg/custom/text-filter.svg
2) Open another (empty) tab
3) Switch back and forth between the tabs, for example using cmd-shift-[ and cmd-shift=]

Results:

The text gets more blurry each time, and the paint takes longer each time.

Expected results:

The visual output should be the same each time and should not take any longer.

Looks good.  It's an old if statement, which seems to have lost it's actual content (I think it used to have a NSLog in that case).
