@bhackett1024 do you have any idea where we could look for the bug here? This feels like a straight forward fix if we know where to look.

[bhackett1024]

I don't have a good idea, but it should be possible to narrow things down to help figure out what the problem is. It looks like this happens when not recording, is that the case? That would exclude a lot of possible changes right there. Do things work as expected in the ESR build? If so, do they work in a local build made from the upstream ESR branch? If things work then, we'd have narrowed things down to some of the code changes we've made to the upstream branch. Most of those only take effect when recording/replaying, but there are some features I think that are universally disabled like hardware acceleration and APZ (https://hacks.mozilla.org/2017/11/async-panzoom-apz-lands-in-firefox-quantum/).

@jasonLaster This is in the current sprint. What's the next steps here?

I want to get @markerikson's eyes on it, but that's only because he mains windows. It's an edge case setting(high dpi) that's not affecting the core debugging experience, so I'm inclined to move it out of this sprint and into the backlog.

Let me know what you think!

I'm not on HiDPI myself on _this machine, so I haven't seen it. Icebox this.

Update: I did actually have the Replay browser open on my personal laptop a couple days ago and saw this, so I can confirm it's a real bug.
