Therefor the ctor GLPixelAttributes failed and threw the exception: "Caught GLException: Could not find PixelFormat for format and/or type: PixelAttributes[fmt 0x1908, type 0x8368, null]" Solution is to have the GLContext default values pre-validated in the convert(..) method and to use default GL_RGBA and GL_UNSIGNED_BYTE fallback values if not supported. This is most important to be future proof. Later we may shall add these 32bit coding 2+10+10+10 and its reverse. 6308 1 sgothel 2019-09-05 05:39:36 +0200 commit 90760ac8eebe7431ac7392e4ebf3f9009e63cd72
