Hi, Complete app here https://github.com/tace/jolla2gether.git I created a branch "*canvas_crash*" for you. The canvas code is in https://github.com/tace/jolla2gether/blob/canvas_crash/qml/components/ExternalLinkDialog.qml .
To reproduce the problem. 1. Start app and select "Questions" from pull menu 2. Open any question page having picture. E.g. put to search criteria (from pull menu) "summer" and you will see this question https://together.jolla.com/question/44887/high-contrast-ambiences-summer-ready/ which has some pics. 3. Click a picture and you are on the Dialog page where the Canvas is. 4. Now swipe right i.e. cancel the dialog and then click the picture again to enter Dialog page again. Repeat this until app crashes.
