The side texture of the end gateways are displayed through adjacent end gateways, breaking the immersion.

This appears to be an issue with Render Dragon, as mobile devices are not affected.

Notes: This is not reproducible in a regular environment, as end gateways are normally unobtainable and only generate alone. However, it can be observed on maps that use the block as decoration (example: the InPvP minigame lobby) and worlds that had it before due to a glitch (such as MCPE-47174). Point is, it can be seen in vanilla, just not through regular means.
