This bug is for investigating a possible regression for filters that extend the maximum current area. 989414 1 226432 savagobr 2014-03-11 09:26:37 -0700 Created attachment 226432 PoC 993235 2 savagobr 2014-03-21 11:39:20 -0700 There is no spoon, I mean, regression. 993259 3 krit 2014-03-21 12:11:36 -0700 Why is that not an issue anymore?

If the filtered element failed to be draw, we should expect to see a red background. Using either 1px or 100px blur kernel will still run fine (even though the later one will run slower). Which proves that CSS filters are working with big regions/elements. 993302 9 savagobr 2014-03-21 13:36:44 -0700 We don't have a bug report for SVGs. 993473 10 krit 2014-03-22 05:06:05 -0700 (In reply to comment #9) > We don't have a bug report for SVGs.
