Hi Micah,
first, congratulation for running PicoGUI on your Helio/Linux.

No, I'm not familiar with the divnodes.

Great. I'm ready to test it when available. ;-)

Good. Rendering bitmaps is one important thing for Waba.

Good idea.

Let me know when I can then them.

Yes. For the moment, I use PGFX_PERSISTENT to continue my
implementation, and I will try to find the problem later.
Once more, thanks in advance for the help.
