[PD] Getting GL[1286] Error Message in Gem

[Jim Ruxton]

Wondering if anyone knows why I keep getting an error message:

" GL [1286] Invalid framebuffer operation " when using Gem on OSX 
10.14.6 . I'm using the latest version from Deken. This doesn't happen 
in Linux. The gem window seems to render ok but the error must be 
messing with the CPU because it is causing major glitches in the sound.

  I get this error when I try a simple patch such as the circle help file.

Thanks for any advice on this.

Jim
