1258008 - Tab bugged: CSS transitions and animations flickering

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect, P3)

User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160303134406

Steps to reproduce:

- Opened site (It loaded correctly)
- Found a track and pressed play
- Seeked the track (If the track has not buffered, it will keep setting the currentTime to the requested seek position until it is buffered)
- Let the track play to end
- Pressed play to start the track again


Actual results:

- Track did not start playing (This happens on random, so there is no way to reproduce the bug on command), refreshed tab
- On refreshing tab, the splash screen does not fade in correctly, the text in the middle flickers wildly and the splash screen has to be manually removed with firebug.
- All CSS related animation or transitions flicker wildly (This has also happened on SoundCloud.com)
- Refreshing the tab does not fix it, however opening a new tab fixes it.


Expected results:

- Website should have displayed correctly with no flickering
- Refreshing the tab should have done the same.

Do you have a testcase?

No because I can not recreate the bug at will. It does happen occasionally, but mostly with my site.

I tried uploading two video examples (roughly 11 mb) but they were apparently too large. I'll try compressing them and give it another go.

Just upload them on a third-party cloud hoster, like Dropbox or Google Drive.

This RAR archive is corrupt, could you reupload it again, please.

I've reuploaded it, hopefully it works now.

Still broken, just use another hoster maybe.

And if your archive contains only one video file, don't zip it, compression is useless in such a case.
