STR (1) Load http://lab.hakim.se/reveal-js/ in b2g browser (2) Tap through slides I see two kinds of bugs A. Slides transition in but are only partially painted B. Slides use some sort of 2D transition, not the usual 3D transition Sorry for brevity but very easy to reproduce. Might reproduce in fennec but haven't tried. Doesn't look like the transitions are being async'ified.

(tracking? just to it shows up in some bug list eventually.)

Let's find out more about how this works on Fennec and that might help determine if this is a v1 or v2 and beyond bug.

This issue does repro on Build 20130208070201 Dec 5th Kernel. Currently when scrolling thru the slides on http://lab.hakim.se/reveal-js/ it shows in 2D transition and frames are partial panted. Also noticed that the writing for some of the examples are very small and hard to read.

Using fennec 18.0.2, transituion show in a more 3D sense and the transitions are full. Having said that there are graphic glitches of part of the window repainting. See screenshot (lower right corner)

This bug persists in 34.0 (Linux Mint version) Maybe this bug is related to NVIDIA GPU driver bug? CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz GPU: GeForce GTX 970 / proprietary driver 343.36 uname -v: #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014

I'm on Ubuntu 14.04, and I have Firefox 47, and I'm having this issue on transitions. It sometimes shows up repeatedly, but the usual thing that creates it is moving in an orthogonal direction before the slide finishes transitioning on a prior slide change. $ uname -v #138-Ubuntu SMP Fri Jun 24 17:00:34 UTC 2016 $ sudo lshw -short | grep -E "processor|display" /0/5 processor Intel(R) Core(TM) i5 CPU M 460 @ 2.53GHz /0/100/2 display Core Processor Integrated Graphics Controller
