1208989 - Dragging icons in customize mode is very jarring and jumpy

Status: RESOLVED DUPLICATE of bug 1206418

(Core :: Layout, defect)

Description

[Luís Miguel [:quicksaver] (not reading bugmail)]

In the latest nightly when I enter customize mode and try to move any icons in the palette, instead of fluid movements I see jumpy and flickering icons.

Last good build: https://hg.mozilla.org/mozilla-central/rev/37c7812ce0e6d10c7e7182f12e752832835e1d67 [1]
First bad build: https://hg.mozilla.org/mozilla-central/rev/eb30e5ee32f0a11e3df594b5b3e69d0a5566bb63 [2]

Sinker, any chance this was your patches?

Luís, can you doublecheck the same with mozregression against inbound?

Luis, please check bug 1206418, it may be the same problem.
If it's not, a video is helpful.

Indeed, I don't see this issue in the latest inbound. I guess it was the same problem. (I didn't dissect exactly which build/patch fixed it, I don't think it's necessary as it was almost surely bug 1206418 as you suggested.)
