Well known, and happens in other games as well. But no one bothered to make a report cause it was just a performance quirk. Generally it isn't a problem... except for the Ridley fight. Flying enemy + raining = pain in the ass. This is definitely an issue for Linux users who can't jump to Direct3D to avoid this.
The best way to reproduce this is the method the OP describes. Load the below GCI (top save) and look up.

Or you can just use this fifolog. From my testing, the fifolog has the same framerates that I witnessed while testing it. Around 27fps on a 4.7ghz 3570K. I have a hunch that everyone else will get a similar framerate regardless of performance.

Metroid Prime 1 via Metroid Prime Trilogy has the same problem.

This should be fixed in latest master. I'm testing and on previous builds I drop to 30 fps, but on latest build I still stay at 140 fps.

I'm sorry, I didn't put the revision that fixed this for me, https://dolphin-emu.org/download/dev/6cece6b486670dd149c827053a84754c98397ccc/
4.0-315 of the master branch. Creates a native texture pool.

Confirming that the issue seems to be fixed. I just loaded up Prime and ran around Landing Site, and experienced no slowdown attributable to refraction rendering.

This issue was fixed for a while, but the build that fixed it reverted. Heavily encouraging people who are playing this game to use builds before Native Texture Pool was reverted to use it until a more workable solution is finished.

Still not as fast as D3D, but a lot faster now, quite playable even with high IR
Thanks a lot
