What's the problem? Describe what went wrong.
Many times, when I am platforming/running, instead of turning a bit (or 90º, since I am using a keyboard) the game character (Spyro, Spyro gliding, Blink or Chasseur) turns around a full turn.

What steps will reproduce the problem?
Play with keyboard, walk (or move) forward and try to turn a bit. In about ten minutes you will have encountered the issue several times. Probleme is not present on real hardware (and by that I mean this same ISO played on a RVL-001 Wii through Nintendont and a black European Gamecube controller). I can not use the Gamecube controller in this computer since I can not install the drivers due to not having (and not being able to access) administrator privileges. Probleme does not seem to be on Sonic Riders (Europe).

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
At least since 1/12/2019, about release 5.0-11300 and onwards. As of 17/12/2019, latest developpement release is 5.0-11384.

Is the issue present in the latest stable version?
Can not tell.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

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
