Update: I've manage to resolve the issue by having going into the nvidia control panel 3d setting, and telling nvidia to force java to run on the nvidia gpu and allow nvidia's drivers override program settings.
Note: this isn't necessary to do when running minecraft version 1.7.10 and earlier. only the new snapshots require this change.
I just tested in java 8 build 11 64-bit environment and the screen flickering still happens.
Same thing happens to me. I play on switch and I also transferred from switch edition to bedrock on survival. I've made copies and tried killing it multiple times but the egg has never spawned
