Running the Adafruit_CircuitPython_FunHouse simpletest, the display starts clean, but accumulates an increasing number of "glitches" at random locations in the regions not being updated with new values.
Is anyone else experiencing this?

Re: FunHouse display accumulating glitches
Weird. Can you try also with this SelfTest UF2:

It's written in Arduino, but you don't need to actually have Arduino installed. Just put the board in bootloader mode, same way as with CircuitPython:

and then copy the SelfTest UF2 over.

Re: FunHouse display accumulating glitches
I see the same thing with the CircuitPython demo.

Re: FunHouse display accumulating glitches
As expected, I do not see glitches on the Arduino test program, only under CircuitPython.
I suspect it is a problem with the CircuitPython handling of the display (maybe timing or interrupts?).
Do you recommend we avoid CircuitPython and program with Arduino instead? -- BANNED, if so.

Re: FunHouse display accumulating glitches
Thanks for checking. Just wanted to make sure it wasn't hardware related. It did not look like it, but wanted to verify.
Seems like something is happening with CircuitPython and we'll take a look into this.

Re: FunHouse display accumulating glitches
Please try CircuitPython 7.0.0-alpha.5 or later, which has tried to fix this.
