I got this assertion failure when starting up gzdoom with vid_enablevulkan turned on and the GPU doesn't support Vulkan:
Code: Select all
gzdoom: /home/edward-san/zdoom/gzdoom/trunk/src/posix/sdl/sdlglvideo.cpp:120: void Priv::CreateWindow(uint32_t): Assertion `Priv::window == nullptr' failed.
My GPU is Intel Sandybridge Mobile Graphics (2nd Generation era). I'm not sure it's due to Vulkan backend. It seems as if the backend tries to rebuild the SDL_Window instance, when it was already done during the I_InitGraphics call in v_video.cpp line 686, while the crash happens in a subfunction of Video->SetResolution() in v_video.cpp line 688, two lines after I_InitGraphics. Backtrace is below:

[Edit] If the assertions are disabled (Release mode), two windows are created. The first one is empty, the second one shows the actual game.
