Screen Glitch Bug Following Canvas



I’ve been trying to debug this for a few weeks with no luck, so I figured I would turn here. My app has a view that contains a canvas utilizing the signature_pad library. Then, the view gets set to a text input and when the input is touched on Android only the following glitch occurs: view here.

This bug only seems to occur on Android and when a release build is used (doesn’t happen in debug or on emulators). So my thinking was perhaps it’s an optimization bug?

Also, I’ve tried hiding the canvas when the view isn’t active and using the ngIf directive to remove it from the DOM, no luck.

Any suggestions on how to debug or possible fixes?

Much thanks.
