Image stutter or flicker on loading

more options

Photo galleries on my website stutter or flicker when moving from one image to the next. This is a new problem -- since last week -- and can be seen on the auto-play gallery on the home page: http://www.dgiphotography.com as well as on other galleries. The galleries are created using JuiceBox-Builder Pro 1.4.4.2 and Dreamweaver CS6, and viewed on either a MacBook Pro or a Mac Pro (OS 10.11.4). This problem shows up ONLY on a Mac (no problem on a PC) running Firefox, while Safari, Chrome, and Opera all show the galleries perfectly, no problem. I am running Firefox 45.0.1 and have tried refreshing, trashing preference files, etc. -- no joy.

Chosen solution

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: "3-bar" menu button or Tools > Add-ons > Appearance
  • Do NOT click the "Refresh Firefox" button on the Safe Mode start window

Try this: Go to Firefox Preferences, select Advanced, then uncheck the box: Use hardware acceleration.

Sorry - I should have mentioned that I had already tried unchecking hardware acceleration. That doesn't eliminate the problem.

Starting in safe mode solved the problem. I switched off hardware acceleration and re-started in normal mode. The problem did not reappear, even though previously switching off hardware acceleration had not solved the problem. But things are OK now -- thanks!
