Valentin, Yes, Gizmo is utilized here. No, it doesn't do as you assert in terms of its functionality (doesn't come close to it), so while your problem may go away without Gizmo present, there is likely something else you have conflicting with this issue as well. Unfortunately, there's not a whole lot to go off of based on your description here, and as this is the first time we're ever hearing of this I don't believe it's a wide spread issue. If you're willing to help us, we'd love to get involved in this to help you! A great test would be to install X-Plane's demo version as a clean install somewhere on your computer. After that, install ONLY the CRJ (this will install Gizmo as well), and see if the livery switching issue still happens in that instance. Thanks for any info you can help to provide! P.S. Can you please shed info as to what your system hardware specs are? To be very frank, this sounds more like a lower end hardware issue that's getting it's memory pushed to the max rather than a specific issue correlated to Gizmo itself.
