Yes, changed to 9341_t3n - not sure what that does differently.
The ON SCREEN 9341 is PERFECT - that screen shot is what Processing presented.
It seems to not use current buffer but Snap another Image - maybe it is getting it not drawn sync'd or ready for use?
That was the reason for using SerialUSB1. I make sure the sketch is running and the image window appears and then send the data from Arduino sketch with p command in main serial window. Did it a whole bunch of times with an issue. Not sure what the problem could be. May have to change writeRectangle to writeRectangle(CENTER, CENTER). But looks like the resolution that is getting sent is not 320x240 - should be filling the rectange.
