@zerophase I can't open your link, can you paste here or give another link?

This is enough to recreate the Unreal startup issue if you want to track down where in their version of SDL2 everything breaks.

The SDL2 being used by Unreal has issues with being initialized properly. I tried getting their step into third party code working on Linux to no Avail. It has something to do with SDL2 not being able to detect the proper video settings.

I tried filling a bug report with Epic, and got an email response saying, "works as intended."

Found a working workaround for the freezing issue!

thx to thejustinwalsh in Unrealforum.

Works in 4.24.1-release

in LinuxApplication.cpp at line 54-56:

commenting out:

check(InitializedSubsystems & SDL_INIT_JOYSTICK);

check(InitializedSubsystems & SDL_INIT_GAMECONTROLLER);

check(InitializedSubsystems & SDL_INIT_HAPTIC);

in LinuxPlatformApplicationMisc.cpp line 287:

change:

if (SDL_Init((SDL_INIT_EVERYTHING ^ SDL_INIT_AUDIO) | SDL_INIT_NOPARACHUTE) != 0)

to:

if (SDL_Init(SDL_INIT_TIMER | SDL_INIT_VIDEO | SDL_INIT_EVENTS | SDL_INIT_NOPARACHUTE) != 0)

compile

run

done.

@Shatur So its seams limited to the 1070. Good to know. :-|

Shatur commented on 2020-01-05 16:26

@Slasher006, @niqingliang2003, very strange, I also use KDE with Nvidia, but everything works as it should.

Slasher006 commented on 2020-01-05 12:27

@niqingliang2003 No patch yet. I am trying to get that workaround running. No luck so far :-|

4.24.1 report: lag every 3 seconds on kde/nvidia1070 still there.
