can't instantiate a second CLVGL class on second framebuffer (Pi4)

Forgive me if this is the wrong way to report this, but I'm trying to sort out why I can't seem to instantiate a second CLVGL class on a second CScreenDevice or CBcmFrameBuffer. My first CLVGL object works fine on the primary display, and I can initialize and use the standard SetPixel methods on the second CScreenDevice, but if i create a second CLVGL (or CUGUI class for that matter), then the kernel fails to boot. I'm using the network bootloader to push the kernel8-rpi4.img as I develop, and when I upload, nothing happens. If I remove the second CLVGL or CUGUI objects, then the kernel boots and runs fine. Any thoughts as to what might be causing this?

This is the right place to ask. Unfortunately it's only possible to display a GUI on one frame buffer. More is not supported.

Thanks for the confirmation Rene. And I appreciate everyone's work on the library. This has been a very intriguing learning experience for me.
