>>By the way, I set "AccelMethod" to ”none” instead of “glamor” also makes the screen became normal. but OpenGL app run with Error:



>>X Error of failed request:  BadDrawable (invalid Pixmap or Window parameter)

 >> Major opcode of failed request:  153 (DRI2)

 >> Minor opcode of failed request:  8 (DRI2SwapBuffers               )

 >> Resource id in failed request:  0x1e00002

  >>Serial number of failed request:  115

  >>Current serial number in output stream:  116



>>If it is most likely a Mesa or LLVM issue, how can I debug or do some trial ?

>>Thanks.
