The newest 19.0.0 mesa works well so I've bisected this. It was fixed by commit: 468a2b6525f3b1e950d8b14138ccf62227aab73a is the first fixed commit commit 468a2b6525f3b1e950d8b14138ccf62227aab73a Author: Jason Ekstrand <<a href="mailto:jason.ekstrand@intel.com">jason.ekstrand@intel.com</a>> Date: Mon Jan 22 23:40:48 2018 -0800 i965/miptree: Add an aux_disabled parameter to render_aux_usage Only one of the callers of intel_miptree_render_aux_usage actually took brw->draw_aux_buffer_disabled into account. This was causing us to ignore draw_aux_buffer_disabled for the intel_miptree_prepare_render. This isn't a problem because the draw_aux_buffer_disabled entry was set during texture preparation and we already did the resolve at that time. However, this also meant that the aux_usage we were passing to brw_cache_flush_for_render and brw_render_cache_add_bo was wrong so our automatic cache flushing around aux_usage changes wasn't happening. This was causing GPU hangs in Oxenfree.
