This was tested using kernel 5.0rc6. The userspace driver has been patched to prevent itself from closing a handle too soon because of unusual kernel allocation behavior (which caused the original bug), but either a problem in the driver or in the DRM/GEM system causes corruption to form in drawn buffers and possibly in other memory with certain driver operations. I believe this to be caused by the same state which triggered the original bug.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
