Emulator

Game Name?
Spyro: A Hero's Tail

Game ID?
G5SP7D

What's the problem? Describe what went wrong in few words.
Messed up bloom/HDR post processing. The game makes extensive use of glowing objects, and it achieves this by overlaying a full-screen "glow map" over the rendered scene. The problem is that the glow map contains smears and weird artefacts that do not belong, and sometimes the glow map isn't even aligned correctly with the objects it's supposed to make glow.

What did you expect to happen instead?
The objects should glow correctly, i.e. no smears or misalignments.

What steps will reproduce the problem?

1. Start Spyro: A Hero's Tail and get through the first cutscene.
2. The game has a lot of objects that glow. They're everywhere, the nearest object at the beginning of the game would be located here (where the arrow is on the map):

3. Notice the smears of her wings.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?

Does using an older version of Dolphin solve your issue?

Please note that EFB Copies was enabled when recording this.

I noticed that disabling EFB Copies (while the game was running) caused the glow map to stop being updated, that is, whatever was on it right before disabling the option would always be overlaid onto the screen, no matter where the camera was pointed.
