KTX files are losing their URL extensions

Given an allowed texture format collection of ‘astc’, ‘etc2’, ‘dxt’, we’re seeing malformed urls.

We saw this issue a while ago and thought it might have to do with adding a cache buster string like http://www.example.com/myimage.png?v=1

Since then we’ve removed this query string but we’re still seeing this issue. In our logs, there are requests for something like http://www.example.com/myimage.

It’s not a reproducible thing but it’s our most common error when failing to load textures.

This one is going to be tough if there’s no repro nor any hint for what could be wrong…

Maybe one thing to check would be to simulate a context lost and see what happens (don’t know how to simulate that, however…).

We thought of this, so we added logging to catch context lost events, thinking this was related. However, the users who see this problem were NOT losing context first.
