After the most recent Mesa update:

kwin stopped doing compositing/acceleration on a laptop with Intel Haswell
graphics. KInfoCenter shows:
Vendor: Intel Open Source Technology Center
Renderer: Mesa DRI Intel(R) Haswell Mobile
OpenGL/ES version: 3.0 Mesa 18.0.0
Kernel module: i915
The reason seems to be that kwin is looking for a 32-bit frame buffer, while
the Intel driver is creating only 24-bit (see log excerpts below).
Is this a bug, or a configuration error? Any advice?
