Enableing ShadowPrimary, some OpenGL applications looks better. But some app still has problem: [cid:image001.png at 01D374F4.41DB2700] By the way, I set "AccelMethod" to â??noneâ?? instead of â??glamorâ?? 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 ?
