Firefox 33 Beta 8 processes keyboard events very slow
(Core :: Graphics, defect)
(Reporter: frfxtst, Unassigned)
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0 Build ID: 20140923175406 Steps to reproduce: Open the add-ons dialog via the "Tools/Add-ons" menu and go to the "Extensions" section. Press the "alt" key. Type some text in the search box. Actual results: It takes very long until the menue is shown. Typing is pretty sluggish. When I try the same with Firefox 33 Beta 7, everything is fine. I found this problem when I tried my add-on EPUBReader with this Firefox version. When I use the add-on everything is very slow, e.g. paging, opening/closing the table of content tab. Using Firefox 33 Beta 7 everyhing is fine. As I assume, that many other add-ons are effected, the priority of this problem is in my opinion high.
Just to make it clear: this problem occurs without any add-ons installed.

because this is only occurring while layers.offmainthreadcomposition.enabled is set to true (discussed in #firefox on irc), this is probably (re?)introduced by bug 1074045. needinfoing bas schouten because bug 1074045 was assigned to him, if there is more troubleshooting information that would be helpful gathering here...
I just made some further testing with ff33 beta 8. It seems to be that typing is very sluggish in general. No matter if i enter an url in the url bar or type some text in an input field on a website. So it's really not much fun using this version. I guess I'm not the only one with such problems. Would it be possible to set layers.offmainthreadcomposition.enabled back to "false" in the final ff33 release?

I'm experiencing similar keyboard input events being very slow to be processed, with FF 33.02 on windows 7. This was also reported independently by other users into https://support.mozilla.org/en-US/questions/1022825 I'm experiencing this lag when using the address bar, or using web sites (e.g. google docs) which become unuseable. Not better after starting from a fresh profile, updating all plugins. I thought it could come from by computer, but the problem does not reproduce in chrome or other windows apps, only in FF
