Description Christopher Dissauer 2008-04-24 11:59:35 UTC 
The function intelEmitCopyBlitLocked() (in file intel_batchbuffer.c) expects source and destination pitch in pixels, but the call from do_draw_pix() (in file intel_pixel.c) retrieves the screen's pitch via intel->intelScreen->front.pitch, which is specified in bytes.

The same problem is also evident in intelTryReadPixels().
