Next thing I'm going to try > is to dump all shaders from first test and see if I could figure out which > ones might be related to the hang. i tried and found the hang related to below shader files(tried to comment the share files loading, the hang would not be reproduced): /sdcard/androiddata/shaders\floop_tesselation.glsl_shadow_vs_vp /sdcard/androiddata/shaders\floop_tesselation.glsl_shadow_tes_tes /sdcard/androiddata/shaders\floop_tesselation.glsl_shadow_tcs_tcs i am trying to dump those files and to see if there are some related finds.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
