If you guys can fix it sooner. Please let me know so I can repull it… Want to check out this build.
Build blew up. Will post a fix, and maybe a pull request if you guys want. Looking to see if I can get it going.

Programs/UnrealEngine-master/Engine/Intermediate/Build/Linux/B4D820EA/CrashReportClient/Shipping/Slate/Module.Slate.1_of_5.cpp:8:

UnrealEngine-master/Engine/Source/Runtime/Slate/Private/Framework/Application/SlateApplication.cpp:3822:65: error: too few arguments to function call, expected 3, have 2
Renderer->PrepareToTakeScreenshot(ScreenshotRect, &OutColorData);
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~                              ^

UnrealEngine-master/Engine/Source/Runtime/SlateCore/Public/Rendering/SlateRenderer.h:426:2: note: 'PrepareToTakeScreenshot' declared here virtual void PrepareToTakeScreenshot(const FIntRect& Rect, TArray<FColor>* OutColorData, SWindow* InScreenshotWindow) {}

No Clue if I did this right, but possible fix is on line 3822:
Crash report client builds without complaint at least so far.

SWindow* SlateWindow = WidgetWindow.Get(); 
Renderer->PrepareToTakeScreenshot(ScreenshotRect, &OutColorData, SlateWindow);

Well, I guess my fix was correct, but my changes where already patched in the git… Somehow I pulled the regression. Not sure what happened there. I pulled after the commit. But anyways. The new version on master jives with mine.
