Segmentation fault on startup

Overview

Segfault in SDL when trying to call SDL_GetWindowSurface(). This only happens on my desktop. It runs fine on my laptop. Tried reinstalling libsdl. I've had a few cases where it doesn't segfault but just testing it again right now I'm not able to get it to launch. The window appears briefly but I think it's crashing before it has a chance to ever draw something, so it's segfaulting the first time SDL_GetWindowSurface() is called.

Crashes here:

OpenChart/OpenChart/src/UI/Windows/SDLWindow.cs

Line 68 in b3b4409

Surface = new Surface(SDL_GetWindowSurface(Handle), freeOnDispose: false);
