KMS bogus dumb buffer
The KMS module is allocating a dumb buffer for unclear reasons. There are a number of problems with that:
- It wastes precious memory (some DRM driver use CMA or other constrained memory pool), leading to avoidable failures.
- It does not care for the format of the buffer. I guess it's assuming implicitly that RGB32 works... ?
IMO the window provider shouldn't do this at all.
