This is kind of interesting. 13 instances, all in May 2018, all on Windows 10, but on a variety of graphics cards. But all failed to compile the debug_font shader.
Maybe this is a permafail but only happens when the WR profiler is turned on. It doesn't look like the DebugRenderer is used in the normal codepaths.
