[Bug 101885] [skl] Kwin crashing

--- Comment #1 from Topi Pohjolainen <topi.pohjolainen at intel.com> ---
Looking at the backtrace it looks like there is some sort of of clean-up going
on, destructor for KWin::SceneOpenGL::Texture getting called. What surprises me
a bit is that it seems to kick off rendering with GPU as
isl_emit_depth_stencil_hiz_s() gets called to setup the hardware.

For normal rendering there is its own path for setting depth+stencil and ending
up here means that the GPU is being setup for blorp.

Anyway, is ~Texture() really suppose to render something and more importantly
is the driver context still suppose to be valid at this point. Looking at:

6  0x00007f294cfdb534 in isl_gen5_emit_depth_stencil_hiz_s (dev=0x0,
batch=0x1344830, info=0x1) at
/var/tmp/portage/media-libs/mesa-9999/work/mesa-9999/src/intel/isl/isl_emit_depth_stencil.c:67

All three arguments are pointers and must be valid, first is simply NULL and
third clearly invalid "0x1".
