What's the problem? Describe what went wrong.

In the basement of Link's house, there is a mirror to the left of a treasure chest. When you walk up to the mirror with the lantern Link's reflection should appear, and without the lantern only a slight glint from the Master Sword is visible. However, in Dolphin the mirror isn't always there: swiping the lantern and standing in a few places close to the mirror causes Link's reflection to flicker momentarily, but for the most part the pane of the mirror fails to render at all and you can see straight through it.

What steps will reproduce the problem?

Obtain the lantern, go into the basement of Link's house, and walk up to the mirror in the top right corner of the room. Swipe the lantern to see his reflection flicker.

Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?

Dolphin 4.0-9328
Dolphin 4.0-9442

I tried to test 4.0.2 but it failed to build on my computer.

What are your PC specifications? (CPU, GPU, Operating System, more)

i5-4690K, GTX 970 with proprietary driver, Debian Sid 64-bit

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I tried testing with various other settings (single/dual core, no/virtual/realXFB, fast depth on/off, native res/upscaled, msaa on/off) and none of them made a difference.

I am also not aware of any other mirrors like this one in the game. Searching for anything along the lines of "twilight princess mirror" just gives a ton of results about the Mirror of Twilight.
