We're experiencing the same when switching between GBP and JPY currencies:

Some workarounds that I know of to prevent this issue from occurring is to:

1. Disable the block cache (BLOCK_HTML)
2. Edit Magento\Framework\Pricing\Render\PriceBox and either:
   • set the DEFAULT_LIFETIME to 0, or
   • just force getCacheLifetime to return 0

I tried writing an extension to override this behaviour, to no avail (I might be doing something wrong LOL). But it still doesn't solve the root cause of the problem.

Fix is delivered to mainline. Closing the issue.
