… because quite a few of the skins I had looked at had the wrong settings in the INI file.
Just curious, what sort of wrong settings have you observed in these VU meter skins?
Would they not also come to light when used in AIMP? (and receiving some corrective complaints there?)
Mainly the minlevel setting. But admittedly I didn't check a large amount of skins, it was really just half a dozen and I think at least half were wrong. I'm not sure how AIMP uses that setting. I only use it to keep the needle at the MinAngle if the peak reading is below the MinLevel. I expect a lot of users don't check their accuracy so probably didn't notice any problems.
I posted into the other thread about the display issues with your skins, I'll have a fix for AL-65 Elemental in the next version but DejaVU Void Red is displaying correctly for me (no missing pixels on the right side). I expect you may have just experienced a glitch in the draw window which happens occasionally when resizing panels, altering the size slightly or restarting Musicbee usually fixes it.
