Unfortunately the bug report does not indicate what video driver is in use, but presumably it's one of the open source drivers which is using Kernel modesetting. Since the kernel does modesetting, issues like this with the monitor modes or resolution or output enabling really are kernel drm bugs now. Sorry for the pingpong.
