Inkplate 10 showing vertical lines and darker spots on display

Customer:

I have an issue with my Inkplate 10 that causes vertical lines and darker spots to appear over time, even when nothing is being drawn to it. Is this caused by incorrect drawing methods, or is it a problem with the panel itself?

Which version of the library are you using?

This problem was fixed in library version V5.5.0. Please update to that version and check the image.

Soldered Support:

The latest version of the Inkplate library available in Arduino is V5.0.0. We have made additional releases, but these are not yet updated in the Arduino library manager. You can download the Inkplate library directly from our GitHub repository and install it manually in Arduino, or wait a few days until it becomes available through the Arduino library manager.
