Firefox 13 new default smooth scrolling leads to very slow grid scrolling

[Superfluoussss]

Also had the same problem methinks. Although I also had TDRs and one BSOD when I upgraded to Firefox 13. It would scroll slowly I'd try to scroll faster and it would freeze then crash. Had to reinstall my graphics drivers and I'm not sure if it's related to the smooth scrolling. I'm on Windows 7 64-bit and my GPU is a GTX 460 M.

I can also confirm the bug.
Even if I change the settings and turn of smothing, it seems to scroll very sluggish.
Do you have a workaround for this or is more a Firefox bug?

... but if I disable the hardware acceleration option from the same settings option block(Settings->Advanced->Browsing), then it works normal as it should. This happends on Win7, Firefox 13.0.1

Don't believe this is a Sencha issue and I can confirm seeing the scrolling problems in numerous other non-Sencha based sites since FF 13 came out.

It's a firefox 13 issue, not an ExtJS one. Try to play with the advanced settings -> general -> browsing from firefox 13, it's working for me on windows 7 - 64.

I can't agree with you, it's Extjs issue, because "very slow grid scrolling" appears only in infinite-grids, just try simple grid-examples from sencha-documentation <-- they work
