This issue was reported by a user on the now retired Google code repo.

DogLcd example sketches work with an arduino Lenoardo but not with a arduino Mega2560 (no further information available)

I wasn't able to replicate the problem with a first generation Arduino Mega. The status of the issue with the original poster is unkown.

The LICENSE file in the repository is in conflict with the LGPL header at the beginning of the actual source code.

The library supports the creation of custom charcters with the lcd.createChar() function. But the new character is not visible on the display immediately. The user must call, one of the funtions lcd.home()or lcd.setCursor()after the character creation.

Reason for this error is unknown.
Workaround :
Define characters in the setup() function of the sketch and call lcd.home() at the end of setup().

I'm using a teensy 3.6, which is programmed using the arduino ide. When the clock speed is below 70MHz the lcd functions perfectly. Above that characters flood the screen. At max speed (180MHz) the screen doesn't turn on. Please provide some insight on how to resolve this problem.

This seems to always send 0x1D but according to the datasheet that came with my display the bias set command should depend on both model and voltage. 0x1D is only the correct value for a DOGM163 at 5V.
