Extreme slowness when using ezoe in full screen mode

    Details

      Description

      When editing content with eZ Online Editor in full screen, the browser will start to display extreme slowness and eventually freeze (at least for some time).

      Internet Explorer 8 is more prone to this issue, but it will also happen in Firefox (I didn't test in Chrome).

      Steps to Reproduce

      • Create a new ContentObject and at some content, preferably with a lot of formatting tags. Please check the attached file – ie8Content.txt
      • Start to type fast, and click on the buttons to change the formatting by adding and removing bolds, italics, underlines, superscripts, etc...

      At this point you will start to notice that the characters start to display a delay, before actually be displayed in the text area.

      • Continue to type fast, clicking of the format tags to change the format.

      You will notice that the browser eventually will freeze for a long time – 30 seconds or more – and may crash or display erratic behavior like not being able to move the cursor along the text, or to scroll the text area.

        I can't reproduce the issue on IE9, Firefox and Chrome.

        IE8 javascript's engine is known to not be very optimized. So in order to have decent performances with this use case you will need a very powerfull computer.

        I'm afraid we are in a situation where you have to upgrade your computer or your browser (with any of the one listed above).
