6 is ERROR_INVALID_HANDLE, so that seems to be the same failure that was being investigated in bug 1120485 (which added the assertion that's failing here) and resolved incomplete.

:jld, could you have a look please?

This is probably the same underlying issue as bug 1120485 and maybe also bug 1564899 comment #2.

I suspect the cause is a double-CloseHandle somewhere else, and HANDLE value reuse (which is a thing) causing it to sometimes close unrelated handles, which means we have essentially no way to find out where the problem is without STR.

Priority: -- → P5

Also let's maybe not title this bug with a very general message that means “assertion failure in code written by graphics people”, nor use it as a crash signature.

Crash Signature: [@ CrashStatsLogForwarder::CrashAction(mozilla::gfx::LogReason)]
