What's the problem? Describe what went wrong.

It's a graphical glitch. The image is slightly shifted to the top left.

What steps will reproduce the problem?

using moves that have visual effects "on the camera" (see attached video), e.g. Sunny Day or Muddy Water

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Is the issue present in the latest stable version?

tested 10967, was bad

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.)

tested 1632, was good
tested 1635, was bad
Which leads to this merge request apparently being the culprit: https://github.com/dolphin-emu/dolphin/pull/4574

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

I attached a fifolog. It's 3 frames at the end of Muddy Water's visual effects.
I also attached a short mp4 showing the problem and screenshots from builds 1632, 1635, and their diff.
