Defect - [8
.1] Metro Firefox works very slow compare to desktop Firefox for latest nightly
User Agent : Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:25.0) Gecko/20130715 Firefox/25.0 Build ID: 20130715030202 Tested on Windows 8.1 preview using latest nightly from ftp://ftp.mozilla.org/pub/firefox/nightly/2013/07/2013-07-15-03-02-02-mozilla-central/ Metro Firefox works slowly. It is taking long time to open any page. Desktop Firefox works fine for the same build.
I installed Windows 8.1 again and installed new nightly. It was working fine. This issue can be reproduced when device is not used long time and nightly is open so when any one start using it. Firefox metro works slowly. Device needs to be restarted.
It looks like restarting the device doesn't affect Metro Firefox performance.
I can confirm this on my 8.1 device but I see similar problems with other apps on 8.1. We need to understand what's going on here. How can I help if I have an affected machine (up to and including putting the device in the mail and sending to a dev.)

8.1 is a preview release, we might want to wait until we have an rc candidate. Some other bugs related to 8.1 (see bug 890829) are already seeing fixes in newer builds.

I looked into this and the reason may be because we're getting blocked d2d whether or not OMTC is enabled. So we're relying on GDI for OMTC and I think that's causing slowdowns and other issues. I'm going to track / fix those in different bugs in case it's not related to this bug, but if that ends up being it, then we can mark this as resolved/wfm eventually.
Seems like the same thing to me, undupe if I'm wrong.
