Sorta like a screen shot, you cant move the scroll bar and you can't interact with any input boxes.  Other than that the rest of the program seems to work correctly... you can change tabs and min/max the program ect...\r\n\r\nIn v37 you can reload the page to recover the page after a crash. but I can't to do this 100% of the time in v39\r\n\r\nIts seems that 60% of my beta testers love v39 with very noticeable speed improvements...  while the other 40% hate it and literately can't run it with it crashing by freezing  the scroll bar and the content.  I have tried every settings that I know of to fix this but it keeps happening.\r\n\r\n11 JAN 2015 Master using default browser settings works perfect.\r\n\r\nWhile the testing the following\r\n\r\n24 JAN 2015 Master\r\n30 JAN 2015 Master\r\n08 Feb 2015 Master\r\n\r\nSuffers from this unusual freezing issue.\r\n\r\nSo Far I can only reproduce it on on Dell Latitude Laptops with Intel Graphics cards.. some of my users have reported it on different models made by dell that also have Intel Graphics cards.  I can't really be sure if it's 100% related to either dell laptops or Intel Graphics cards.\r\n\r\n\r\nHere is how I reproduce the problem\r\n\r\n1.  You need a dell laptop I am using a Dell Latitude (made in 2009) using Windows 7 Home with 4 gigs on a 64 bit OS.  I am compiling 08 Feb 2015 master to target C# 4.0 .NET (Full) 32 bit. using default browser settings.  I am removing the 4.5 .Net requirements by commenting out those features that use anysc\r\n\r\n2.  Open up 19 tabs and do a Google search then switch tabs until every tab has search output.  If it does not happen on first cycle..  try again with a different search.\r\n\r\n(Note using 11 Jan 2015 master I can safely have 30 tabs with out issues) \r\n\r\nHas anyone else experienced this issue ?  \r\n\r\nThanks.\r\nDavid"},"comment":{"url":"https://api.github.com/repos/cefsharp/CefSharp/issues/comments/84347684","html_url":"https://github.com/cefsharp/CefSharp/issues/802#issuecomment-84347684","issue_url":"https://api.github.com/repos/cefsharp/CefSharp/issues/802","id":84347684,"user":{"login":"daveaton","id":3393813,"avatar_url":"https://avatars.githubusercontent.com/u/3393813?v=3","gravatar_id":"","url":"https://api.github.com/users/daveaton","html_url":"https://github.com/daveaton","followers_url":"https://api.github.com/users/daveaton/followers","following_url":"https://api.github.com/users/daveaton/following{/other_user}","gists_url":"https://api.github.com/users/daveaton/gists{/gist_id}","starred_url":"https://api.github.com/users/daveaton/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/daveaton/subscriptions","organizations_url":"https://api.github.com/users/daveaton/orgs","repos_url":"https://api.github.com/users/daveaton/repos","events_url":"https://api.github.com/users/daveaton/events{/privacy}","received_events_url":"https://api.github.com/users/daveaton/received_events","type":"User","site_admin":false},"created_at":"2015-03-21T14:03:41Z","updated_at":"2015-03-21T14:03:41Z","body":"Just an update..  I have been playing around with 2272 and it's super fast..  I am still waiting for the users who have had the freezing issues in the past.\r\n\r\nThe freezing issues with v37 after 12 Jan 2015 and all of v39 I suspect deal with the input box such as a chat input box nested in frames.   I have a sneaky feeling it's has something to do with focus or keyboard commands because It actually happened on my machine and when I gave focus to a input but and tried to type the screen froze just like my users complained about..  while trying to figure out when went wrong after a few minutes it unlocked it self.  And slowly began to show the typed text  1 letter at a time with 5 to 10 seconds pause between.  I guess it was doing something with the text...  I typed  \"how is everyone one\" in a chat box and it took 10 min to complete the sentence and unfreeze. then all the animation and rest of the page began to function normally..  I tried to type again and it happened again.\r\n\r\nSince that happened I was not able to reproduce the issue again on my machine.  I have not changed any settings since that time. \r\n\r\nThis was why the page never recovered it self because it did not actually crash, something was just keeping it busy.   I do my subscribe to any handlers with keyboard commands such as the dictionary or focus that I know of.  \r\n\r\nIf I get any reports on the 2272 for my problem child clients I will weed out those features 1 by one and report back.\r\n"}}
