(I was going to say "update to this post" with a link, but I can't find any previous post discussing this. Maybe I only thought about blogging about it.)

1. The reason that the brightness level Windows is stuck on is inconsistent: it's because it's stuck on *whatever brightness Ubuntu is currently set to*. (I routinely change my screen brightness based on ambient light levels, in addition to redshift.)
2. The time-zone issues† only happen if I go to Windows from Ubuntu, not if I reboot Windows and go straight back to Windows.
3. Ubuntu, upon going there from Windows, has mirror-image time-zone issues, though it manages to recover automatically.

I suppose that narrows down the possible causes, though I'm not sure I can be bothered to put any more effort into fixing them. Especially now that I know I can work around the brightness issue by booting into Linux and adjusting it there. And now that the Linux-based Runescape fan community has come up with a more consistently functional client wraparound, so I have less use for Windows.
(Hmm, although now I'm wondering what would happen if I told Windows (but not Linux) that I'm on UTC...)

†Since I can't find a context link, I guess I'll explain here: Windows *claims* to be on Toronto time, but *actually* displays in UTC (which is especially disorienting given how malleable my circadian rhythm is). Manually changing the time only lasts until the next boot.
