Likely Others to be added.
What's the problem? Describe what went wrong.
While playing these games, either they will get stuck in the wrong aspect ratio when using "auto" or they will jump between aspect ratios erratically.
What steps will reproduce the problem?
I will link the individual issues, but most of them will happen right away while a few others are specific to various actions. For instance, Metroid Prime 2's issues only occur when certain effects are on screen, like dust from a enemy coming out of the ground.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
The issue is present in 5.0-12581
Is the issue present in the latest stable version?
Some are, some aren't as the heuristic has changed many times since 5.0.
If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer
We'll probably be moving/attaching fifologs/screenshots as games are added to this issue.

Copying this here in case it's related. Originally posted in #7143:
Super Monkey Ball (GMBE8P) Advanced Stage 10 seems to randomly stretch the screen then quickly return it to the proper size (widescreen mode detection issue?) on 5.0-12369. Dual core only, single core does not have this problem. Let me know if I should file a separate issue for this.

Copying my comment from #12090:
I believe the widescreen heuristic is not fixable without adding per-game settings.
Metal Arms NON-widescreen aspect ratio is 1.25.
F-Zero's widescreen aspect ratio is 1.244.
Certain games have an unusual idea of what "widescreen" is so we can't fix them all with one magic number.

Metal Gear Solid: Twin Snakes is affected, it's always detected as 4:3 even when using the 16:9 Gecko code. The code works fine, but you have to force 16:9 in the graphics option, Dolphin autodetects it as 4:3.
