Does this reproduce with tiling disabled?

Assigned to me just as a placeholder.

Seems to be a partner Apps issue.

No it's definitely not. This isn't reproducible on 1.3 & reproduces on 1.4, which implies a gecko regression. comment 4 clarifies already that this is a regression from tiling.

Probably a dupe of all the other lock failed tiling ones, but let's check.

Comment 8

[Jason Smith [:jsmith]]

Needs a logcat.

This isn't a sufficient logcat - there's very few lines in that log. We need a longer logcat here.

Another thing that one can try - if you enable the developer option "Layers: Draw Tile Borders" and the error lines up with the tile borders that should be visible as thin green lines, then chances are this is tiling related.  If turning off "Enable HW Composer" in the same menu makes the problem go away, then this is will be fixed with bug 984618.

This is not reproducible on Buri with latest master (with or without HWC enabled):
