link text after i updated my unreal engine from 4.14 to 4.15.1 by cloning the github EpicUnreal. it crash every time i start it. i included the crash log. in hope to help the devs make the engine better. note that the engine 4.14 worked fine. i am running the engine on linux. Edited to say: i love epic unreal and i would like to thank them for porting the engine to linux. ---

Hey samuraisora- Can you check the drivers being used? I was able to track down a similar reported issue ([Unreal Engine Issues and Bug Tracker (UE-43136)](https://issues.unrealengine.com/issue/UE-43136)) that turned out to be an issue with conflicting drivers. If your drivers have been updated recently, please try reverting to a previous driver. If your drivers haven’t changed, then it may help to try the inverse and update your drivers. Cheers
