FWIW, I've been seeing some odd 'laggy' behaviour in F21 on my desktop lately, which does mostly seem to be in Firefox. I do have sixteen zillion tabs open, but I do that a lot and it's not happened before, and RAM isn't exhausted (I have 16GB, using about 8GB). I don't have Flash installed. Not had time to look into it in more detail yet, but it does seem like something squiffy is going on. The symptoms are basically that things like switching tabs, highlighting text, copy/pasting, or input appearing after I start to type lag by 1-3 seconds, and sometimes presses/characters that occur within the lag time are lost. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
