Metamask-extension: events are inconsistently triggered

[szerintedmi]

Behaviour of events watch changed recently (unsure from which Metamask release).
When I submit a transaction and it emits an event then my watch function is not called - it used pick up that event. Without Metamask it still works as it used to and as it's expected.

When I refresh the page then suddenly all, even older event handlers called, despite I'm using { fromBlock: "latest", toBlock: "pending" }. It works as expected without Metamask (i.e. only event in latest block is triggered on first load/refresh).

 myContract
   .myEvent({ fromBlock: "latest", toBlock: "pending" })
   .watch(onMyEvent);

seems like we need to resolve latest to the actual block number on filter creation time

found this happening a lot on local dev. solution was to disable extension and re-enable and unlock.

we're still looking for minimal reproduction steps

Hi, I created a repo to reproduce this issue. I don't know if it's the same issue that OP has; if it isn't, I can create a new issue. This reproduction steps are specifically for the issue of MetaMask handling events correctly in Rinkeby but not in testrpc.

The instructions are in the README. Let me know if you need more info.

As of Metamask 3.12.0 we're still having this issue. W/o Metamask it works fine.
Any update?
