I ran into this while looking to verify [Link Removed] at CL 3355923. I logged the issue I was verifying the fix for last night and have not updated anything locally, so the "OpenGL 4.3 not supported by driver" is odd. I wonder is it should be 4.3.X?
Additionally, the splash appears, but is transparent to the point it's almost invisible. You can make out the edges of the rectangular shape.
I'm attaching the backtrace I gathered with GDB as well as the backtrace for all threads.
Repro:
make all ARGS=-clean && make all
./Engine/Binaries/Linux/UE4Editor
Result:
UE4Editor hits an assertion when the Unreal Editor splash starts to appear.
Expected:
UE4Editor opens to the Unreal Project Browser.
