Hi there,

Based on the documentation and reading previous issues, I understand that whenever we detect an image marker for the first time, onAnchorFound gets called once but onAnchorRemoved never gets called, and the marker is continuously being tracked in the background. Continuously tracking multiple markers in the background seems to be affecting performance so I am trying to remove and reload all markers each time a new/different marker is detected.

Like https://github.com/viromedia/viro/issues/776 mentioned, using the anchor's tracking method to hide objects causes the app to lag, so I'm trying to get around it by removing the anchor/marker completely.

@achuvm mentioned in https://github.com/viromedia/viro/issues/270 that it is possible to remove image markers completely. I'm trying to manually remove image markers when a new/different image marker is detected so that onAnchorRemoved is called instead of just hiding them. I'm having trouble achieving this though, is there an examples or sample code of how I can do this? Any suggestions or help will be much appreciated.

I manually removed the image quite literally with my hand. Seems to be the best solution until this gets fixed. Hacky fix... But not an obvious one haha
