I'd tried that GPM with unofficial 87.3 but couldn't get it to work. Thankfully it's possible now on the latest GPM with official Xposed. But only by restoring previous data through something like Titanium because XGPM force closes upon opening so it can't be configured.I installed the version of GPM noted in your image and its working fine again. Thanks very much!
At least I can get a proper view of the album art not cut off now . A request if development resumes if possible is for a black themed interface on the redesigned now playing screen. I've got the app themed black already via Swift Black Substratum but XGPM's screen isn't themed. The bottom mini player is whited out as well.
