Commit 9e158470 set the SDL OpenGL attribut SDL_GL_ALPHA_SIZE to 0 since
the alpha channel is used by Wayland. But for X11 the GLX 1.4 specification
clearly states: "If the requested number of bits in attrib_list for a
particular color component is 0 or GLX_DONT_CARE, then the number of
bits for that component is not considered." So if SDL_GL_ALPHA_SIZE is
0 a framebuffer without an alpha channel is created. This is no problem
on the default GLX module due to a non standard implementation but
manifests with Nvidias GLX module. The consequence are render mistakes
like in game display showing static or the flashlight looking weird.
