I thought this problem was resolved in thanks to @Samuel-Ellicott's suggested solution, but it seems that it was only a temporary fix. When powered off and back on again the dots/lines seem to reappear?

@Kit-Bishop I do have the latest release installed on my Omega. Thanks for your input.

@Samuel-Ellicott You are the man! That worked exactly as explained and all the garbage pixels/lines have been cleared. Thanks!

Also the lit up pixels/lines are still there on the inverse.

It seems to mess up the display. "Test Test" on the left are shown one right above the other. "Test Test Test" on the right should be displayed the same way, but they are being broken up as a result of those already lit up pixels.

Is there something wrong with my OLED Expansion. The right side of the OLED display shows lit up pixels/lines even after clearing or initializing the screen... Thanks in advance for any help!
