Kerbal Space Program

I'm not entirely sure where exactly this bug is (KSP or Unity), but the faulty code is inside the “KSP.x86_64” binary itself.

When setting up the GLX context, you request a backbuffer with GLX_ALPHA_SIZE >= 8. On systems with a higher color depth than 8 (e.g. R10G10B10A2) this fails because A >= 8 is unsatisfiable.

The fix is to remove this constraint from the GLX attribute list passed to glXChooseFBConfig, or set it to 0.

Attached is a work-around that others running into this issue can use in the meantime.

Linux 64-bit 1.1.0 non-Steam. Note that this also affects 1.0.5, although in that version glXChooseFBConfig was linked directly instead of being loaded through glXGetProcAddressARB. (And I still have no idea what line of thought could possibly have prompted that change)
