I was trying to write a simple program to repro the issue but it seems not that easy. It seems basically glReadPixels needs a bound check somewhere. The issue happens randomly (sometimes it won't happen after tens of minutes). I happened to have a 100% repro in seconds save state. However I have difficulty making the trace file < 3M. I am uploading 2 files.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
