Hi, during testing this issue => https://bugs.freedesktop.org/show_bug.cgi?id=111631 I found out that iris throws exception into logs (exactly in the end of the apitrace) /usr/bin/glretrace+0x25fa21 /usr/lib/libpthread.so.0+0x13cff /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: unsafe_free+0x72461c: ../src/util/ralloc.c:297 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: unsafe_free+0x7245ee: ../src/util/ralloc.c:292 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: ralloc_free+0x72450f: ../src/util/ralloc.c:262 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: iris_delete_shader_state+0x8d1cad: ../src/gallium/drivers/iris/iris_program.c:2194 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: iris_delete_fs_state+0x8d1d90: ../src/gallium/drivers/iris/iris_program.c:2225 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: cso_delete_fragment_shader+0x13df75: ../src/gallium/auxiliary/cso_cache/cso_context.c:662 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: free_zombie_shaders+0x4969b8: ../src/mesa/state_tracker/st_context.c:397 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: st_context_free_zombie_objects+0x496b0c: ../src/mesa/state_tracker/st_context.c:431 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: st_flush+0x49527a: ../src/mesa/state_tracker/st_cb_flush.c:60 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: st_glFlush+0x495398: ../src/mesa/state_tracker/st_cb_flush.c:100 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: _mesa_flush+0x1df957: ../src/mesa/main/context.c:1886 /home/den/mesa64/mesa-git-09.09/lib/dri//iris_dri.so: _mesa_Flush+0x1dfadf: ../src/mesa/main/context.c:1924 /usr/bin/glretrace+0xe467d /usr/bin/glretrace+0x5d528 /usr/bin/glretrace+0x5fead /usr/bin/glretrace+0x57f20 /usr/lib/libc.so.6: __libc_start_main+0xf2 /usr/bin/glretrace: _start+0x2d ? apitrace: info: taking default action for signal 11
Please give it a go under valgrind, hopefully you can find a lead to what looks like a memory corruption.
