If the issue isn't present in the latest release, which is the first broken version? (You can find the first broken version by bisecting.

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.
