Emulator

What's the problem? Describe what went wrong.

The vertical filter configuration does not apply to EFB texture copies in the software renderer backend, while working as expected in the Metal backend.

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

Yes. 2603-240

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

Yes. 2603

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

Note the character's skin in the screenshots. The shading is dimmer, because a default copy filter is used. Additionally, the indirection postprocessing effect is miscalibrated

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
