I believe the reason why it works on SKL is that it now uses the TXL_LZ message instead of TXL, which reduces the payload size by two preventing it from exceeding the sampler payload limit. I believe on Gen7-8 platforms sampling from a cubemap array with shadow comparitor on a non-FS stage has been broken since the FS back-end supports non-FS stages... I'll send a patch.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
