A tracking bug that anything keeping us from enable directwrite can block

Related bug: bug 549116

I think someone should contact nvidia and tell them to add a default perapp setting for Anisotropic Filtering on Firefox, as enabling it while D2D is enabled causes some interesting Font blur. http://img.photobucket.com/albums/v253/squall_leonhart69r/Firefox/Firefox-AFOFF.jpg http://img.photobucket.com/albums/v253/squall_leonhart69r/Firefox/Firefox-AFON.jpg http://img.photobucket.com/albums/v253/squall_leonhart69r/Firefox/Firefox-Difference.jpg

Would be better to do these in PNG or some other lossless format by the way. The JPEG artifacts make it harder to see the exact effect.

Same with my ATI card (HD4670). Enabling/Forcing anisotropic filtering in the CCC causes the fonts to blur. I don't think the ATI driver supports app specific settings though.

I sent the ATI driver guy a message over Twitter last night, haven't gotten a response yet, might have gotten lost in all of the noise. I will fire off an email in his direction and point him here and see if he wants to chime in, etc.

I've filed bug 549419 on the anisotropic filtering issue.

Scrolling with DW enabled has suddenly become not smooth. Seems to have been introduced a few nightly builds ago. This is not consistent on every page but happens often enough to be distracting. A page that I'm scrolling will even start out smooth and then all of a sudden it becomes jerky. I can't find any pattern to it. When I turn off DW scrolling is again smooth. The one exception is if I use full page zoom (not text only zoom) on sites with lots of images, like msnbc or cnn.

I have a GTX260 along with the current Nvidia drivers for W7 x64. I turned off everything I could find for AA and AF. The drivers allow you do do this on a program by program basis. So FF is without all of this. Scrolling seems back to normal as a result. Here's what I turned off in the nvidia control panel for Firefox: http://yfrog.com/2tcaptureqnj

OK, still getting jerky scrolling. I find that bringing up the W7 taskbar and hovering over the preview in many cases fixes the scrolling for the page I am on. I'm thinking that the W7 taskbar stuff added to FF might be causing this.

Do you plan on enabling DirectWrite even when D2D is disabled? I installed a nightly and got DW but not D2D (driver blacklist). Performance and text quality were appalling (compared to either GDI or D2D+DW). I don't think it's a good idea to enable DirectWrite without Direct2D.
