Slide transition effect causes slide corruption

[ranr01]

HI,

Not sure if this is a reveal.js bug or a browser issue. Also it happens inconsistently so might be hard to recreate. I just thought to throw it out there and see if others have encountered it and if we can pin point the issue.

The problem is that when using slide in transition sometimes the slide get corrupted and it looks like there are 2 slides on top of each other, or like the last frame of animation did not disappear before the final frame appeared.

It happens more when one goes back and forth along the presentation, and when one actually uses a second display (projector).

My workaround is to use fade in transition.

Sorry I can't be more helpful...
Cheers!

P.S. This is on Linux and Firefox 47

I can confirm that. (Linux FF 47)
It works under Linux with Chromium 51, on my PC.

I made some workaround for Firefox 47+

For me even the fade transition is not working properly in FF48. Thus, transition: 'none' is the only workable solution for the moment.

I'm also having problems with slide transitions on the latest version of Firefox for Mac (all other browsers are fine). Text boxes simply appear after a delay of a few seconds rather than sliding in as they're meant to/did before

I just pushed a fix for this. If you've experienced this issue, can you please try http://lab.hakim.se/reveal-js/ again and see if it works better now? You can try a specific transition by adding it in the query string: http://lab.hakim.se/reveal-js/?transition=convex

Thanks for the fix, works better now but not 100% fixed for me. On FF 49 / Ubuntu 16.04 I see this

for a second when going through the slides. After a second or so, the slide displays correctly. This glitch does not happen all of the time and not on all slides. So far I have only seen this on the "Fragments" slides, and here I can reproduce it, so it might actually be related to the slide content.

Just tried the concave transition and here this happens

In contrast to the slide transition glitch above, this display glitch does not disappear after a second. It only happens on the first time when moving to the slide. When revisiting the slide, this glitch does not appear again.

I think this is resolved with FF57 😃

Since @rajgoel mentioned that he can't reproduce the error anymore, I'm closing this issue for now. This seems like another one of those specific browser/renderer bugs, since people were only able to replicate this with older Firefox versions.
