    Description

      since QtAccessibility in 5.15 has led to many crashes so far, we have updated relatively quickly to 5.15.9.

      the crashes have become less, but the ANR explode by 3 orders of magnitude.
      users report unusability of the app, because inputs are no longer processed and it completely stalls.

      almost all reported callstacks contain QtAccessibility in the main thread

      also noticeable is that almost all of these ANR are reported on android10 sdk29 devices
