I confirmed the fix on 64-bit Ivybridge. Still waiting for a QA update on 32-bit Sandybridge with a modern Chromium. Patch is committed to Mesa master as commit b69c7c5dac4e2615e89cef773173484421830a8f Author: Chad Versace <<a href="mailto:chad.versace@linux.intel.com">chad.versace@linux.intel.com</a>> Date: Tue Nov 18 15:41:35 2014 -0800 i965: Fix segfault in WebGL Conformance on Ivybridge Fixes regression of WebGL Conformance test texture-size-limit [1] on Ivybridge Mobile GT2 0x0166 with Google Chrome R38. Regression introduced by commit 6c044231535b93c5d16404528946cad618d96bd9 Author: Kenneth Graunke <<a href="mailto:kenneth@whitecape.org">kenneth@whitecape.org</a>> Date: Sun Feb 2 02:58:42 2014 -0800 i965: Bump GL_MAX_CUBE_MAP_TEXTURE_SIZE to 8192. The test regressed because the pointer offset arithmetic in intel_miptree_map_gtt() overflows for large textures. The pointer arithmetic is not 64-bit safe.
