Some Android users have experienced a glitched line through their Sketchbook canvas. It may appear vertically, horizontally, or both.
This glitch occurs on devices with a PowerVR GE8320 GPU. The cause is how the GPU handles certain graphics shader code.
The glitched area is a display artifact and will not export as long as it is not selected and transformed. Once selected and transformed, the glitch renders on the canvas and becomes part of the artwork.
We are investigating to see if anything can be done to avoid this issue. If you would like an update on this issue, please email us at firstname.lastname@example.org.
