I was diggin this up further, seems to be weird as seen #7 0x0000000000672568 in read_pixel (dpy=0x3, d=0x7fff4b0c0220, x=1613476428, y=4) at xm_span.c:117 #8 0x00000000006737d6 in get_values_rgba (ctx=<value optimized out>, rb=0x168fdb90, n=1, x=0x167663d0, y=0x1676a3d0, values=0x0) at xm_span.c:4341 -------------------------- from inspecting var values, we know from frame #8 ( get_values_rgba ) (gdb) p n $15 = 1 (gdb) p x[0] // 0x167663d0 $16 = 29 (gdb) p x[1] //0x167663d4 $17 = 23 -------------------------- as seen from code static void get_values_rgba(GLcontext *ctx, struct gl_renderbuffer *rb, GLuint n, const GLint x[], const GLint y[], void *values) { ... case PF_8R8G8B: for (i=0;i<n;i++) { unsigned long p = read_pixel( dpy, buffer, x[i], YFLIP(xrb, y[i]) ); rgba[i][RCOMP] = (GLubyte) ((p >> 16) & 0xff); rgba[i][GCOMP] = (GLubyte) ((p >> 8) & 0xff); rgba[i][BCOMP] = (GLubyte) ( p & 0xff); rgba[i][ACOMP] = 255; } /* * Read a pixel from an X drawable. */ static unsigned long read_pixel( XMesaDisplay *dpy, XMesaDrawable d, int x, int y ) the values being passed to read_pixel are apparently being twisted ?
