Emulator

This issue was reported on the forums by kirbypuff (https://forums.dolphin-emu.org/Thread-custom-ir-issue) and was reposted on GitHub (https://github.com/dolphin-emu/dolphin/pull/2024#issuecomment-76430683) but as far as I can tell no one made a formal issue report for it here on the issue tracker so here it is.

What steps will reproduce the problem?

1. Set the IR to any custom value in the .ini [e.g. 9xIR (EFBScale = 12)].
2. Start Dolphin and run any title.
3. While Dolphin is running, open the Graphics Settings and change the IR to 4x.
4. Now change it back to 'Custom' and close the GFX settings window.
5. Dolphin sets the IR to 5x instead of the custom value(!)
6. If you open the gfx_dx11 or gfx_ogl .ini with a text editor, you can see the change (EFBScale = 8).
