Stack trace??

Comment 4

[Jim Mathies [:jimm]]

nm, thought you were a developer. :) Can you get to about:support to copy paste data, or does it freeze before you get there too?

Comment 5

[Tim Abraldes [:TimAbraldes] [:tabraldes]]

Raul, it might be worthwhile to try launching metro Firefox with a new profile.

Steps:
  - Make sure Metro Firefox is not running
  - Press the Windows key + r
  - That should open a "run" dialog
  - Type %APPDATA% and hit 'enter'
  - Find the 'Mozilla' directory and enter it
  - Rename the 'MetroFirefox' directory to something else
  - Launch Metro Firefox

Also, after more testing situation is:

- very slow, very very slow loading page (mozilla.org eg.)
- search in page not working

I have opened only 2 tabs.
After 5-6 minutes Nightly closed. Mouse freezing. I succeed to closed manually (drag bottom). After reopened Nightly crash.

I try with new profile (eg. safe mode) but same problem.

[Tim Abraldes [:TimAbraldes] [:tabraldes]]

Just to be totally clear, it sounds like you're experiencing the following:
  - Desktop Nightly runs fine.
  - Other Metro apps and other desktop apps run fine.
  - Metro Nightly barely runs (when it runs), and crashes frequently.

Metro Nightly/Firefox doesn't have a "safe mode," but it sounds like you tried running metro Nightly with a blank profile and got the same performance issues. The only thing I can think to double-check here is to make sure that you moved/renamed the metro profile and not the desktop profile.

For the debug info you pasted above, it looks like that came from desktop Nightly rather than metro Nightly. Could you please paste the info from about:support in metro Nightly?

metro is unusable in windows 8.1 preview. Very slow to load pages and render screen. Seems like the same issues from 870390 - Story - Disable forced D2D backend in metro. You have to touch the screen repeatedly to get the screen to refresh.

[Tim Abraldes [:TimAbraldes] [:tabraldes]]

Consolidating a couple bugs that seem to cover the same issue:
  Bug 896627 and bug 893412 are both about the poor performance of metroFx on Windows 8.1. Marking the newer bug as a duplicate of the older bug.

It is likely that bug 907410 is causing a large portion of our performance issues. Marking that as blocking bug 893412.
