Thanks for reporting. 1. Are you able to install debugging symbols, so we get a more detailed backtrace? 2. Do you have a hiDPI screen, i. e. an other screen scale than 100%? 3. I notice the backtrace contains a call to drawImage(), which happens for text annotations. Does the crash happen only when a document or page with annotations is displayed?

That dialog should have a button to install debug symbols, it usually works fine, and otherwise describes what exactly is necessary.
