Font issue in 2IN6_FLASH_V42V?

Posted at:2017-11-07 13:55:30     

Using TextLCDAdapterDemo.ino.

Somewhere when it writes "I'm a string" it leaves a pixel on the line above and is not going away during the demo.

Seems a font issue.

Can you please check

This problem caused by the power supplier, the on board MCU didn't init the LCD panel correctly due to the noise injected from power.

We didn't put large cap on the board in order to keep the profile of module as small as possible.

It occurs in the sketch every time i run it, it is not there from the beginning. It start when writing "I'm"

What you are claiming is that this can occur everywhere on the screen at random. That would have something to with the magic "Q" word.

Please fix it.
