Flowcode Support Board

I haven't tried with fc8 because it's not a package i have;but I tried with the 30 day trial version of FLC9 with AT TINY 85 compilation and I tried to make a small flow with a writing in position 10,10; in debug everything ok but when I compile in hex and load everything with a self-built programmer with arduino who acts as a programmer:
if I make the PB0 LED flash on the digispark board, everything is ok

but if I use I2C to write the text, some pixels are scattered here and there ....


I compile the hex FLC 9 then with AVRDUDESS 2.1 with settings ::
programmer: arduino
mcu: tiny85
preset: arduino as isp
flash: program generated by flowcode 9
com: port where arduino is seen by AVRDUDESS

Hello,

Please can you attach your program and maybe a photo of the display output vs the simulated output so we can see the difference.
