Running the JXRendermark reliably freezes my system when executing the "Transformed Blit Billinear sharp edges"-test.
JXRenderMark can be downloaded from: http://93.83.133.214/downloads/JXRenderMark-1.0.1.zip

Basically the benchmark only executes a series of render-commands, like x11perf does, the test which causes the hang basically looks like the code at the end of the report.

void billinearTransformedBlit(int area, int x, int y)
{
  int maskSize = area/8;
  maskSize = maskSize == 0 ? 1 : area;
  area = maskSize*8;

  XRenderFillRectangle (display, PictOpSrc, alphaMask, &setAlpha, 0, 0, maskSize, maskSize);

  XTransform xf;
 //transform changes omited
 XRenderSetPictureTransform (display, sourceImage, &xf);
 //transform changes omited
 XRenderSetPictureTransform (display, alphaMask, &xf);

  XRenderComposite(display, PictOpOver, sourceImage, alphaMask, backBuffer, 0, 0, 0, 0, x, y, area, area);
