Ridiculous GPU usage (Mac OSX)

[subusername]

Does anybody have any info on how to remedy this?

Opening Subsonic on Mac OSX 10.10.2 (Yosemite) causes my Macbook Pro (Mid 2011 model) to switch to using the discrete graphics card. It also causes the video RAM usage to jump to around 80%, up from around 20%. This occurs every time I launch the app, whether or not I have the control panel/interface open in my web browser, and resolves itself the moment I close the app. I am running no other graphically intensive apps.

This is a serious issue as at times I use image editing software, which uses a large amount of vRAM to run smoothly. With subsonic open there is very little vRAM left available, causing my entire system to slow to a crawl and become basically unusable.

I am using Subsonic version 5.2.1 (build 4427) with a premium license.
