BGE: Removing some glIsEnabled() calls from DisableForText() in KX_BlenderGL.cpp. Use of glIsEnabled() is discouraged since it causes a potential sync with the graphics card. Also, it's faster to just always use glDisable() (even if that feature is already disabled) then to check if it's enabled first.
