Its caused by issues with the GPU and the GPU drivers.
There is three ways to solve this: Wait for them to fix their app (unlikely).
Get a new Android version onto your phone (e.g. LineageOS), or maybe an older version, you need to try.
Or try another app, but that may or may not fix the issue depending on the GPU driver. If you want to try out TelloFPV there is a free demo version in playstore. if it works for you, the full version will work, too.
