Game plays worse/slower in newer versions: Is this considered regression?

Hm. What if you try Direct3D 9 as a graphics backend instead of OpenGL in PPSSPP's graphics settings? Does that change anything for either version?

Also - there were a lot of changes between 1.6.x and 1.7.x. If you even tried one in between, it would cut down on the possible issues by a lot.

https://buildbot.orphis.net/ppsspp/index.php?m=fulllist
v1.6.3-621-g0d7a5cd09 - is basically the same as 1.7.0
v1.6.3-6-gb9388f50e - is basically the same as 1.6.3

So if you were to try one half way in the middle, say v1.6.3-316-g96ff23a47, it would tell us a lot. If that build works just like 1.6.3 for you, then it means none of the 300 changes made before it are the problem. If it already has the problem, it means the 300 changes after it probably aren't the problem.

With another try halfway again, you could cut down another 150 small fry - your power as the hero of the story, the Chosen One who can reproduce the issue.

If we can get it to less than hundreds of changes, it'd be a lot more possible to guess what could've caused the problem. I did review the major changes made in this range and didn't see anything that should obviously cause it.
