Signing messages with full-screen notification breaks UI

[decanus]

Describe the bug

I can't see what is being signed.

To Reproduce
This appears whenever I try and sign a message, I don't know whether its with the eth_sign or personal_sign or eth_signTypedData function (@mbeylin might be able to give the answer). However it happens when I sign a message to login on bounties.network.

Expected behavior
Being able to see what I sign, and the UI not being completely borked.

Browser details (please complete the following information):

• OS: MacOS
• Browser: Chrome Version 69.0.3497.100 (Official Build) (64-bit)
• MetaMask Version: 4.14.0
• Beta UI I think, if it still is?

Woah, super weird, have never seen this before. Couple q's to help us dig in:

Is this happening consistently?
Is this with the standalone popup or the extension attached to the top-right of your browser?
Does it happen with normal transactions, or just with signing data?
Have you used (and resized) chrome pop-ups created by any other apps?

And to clarify, you're on explorer.bounties.network trying to sign in (as below)?

So its on bounties network when you do the login process, it happens when I have a fullscreen window on my mac consistently. Somehow it pops out into a new window when it wants me to sign. I don't know if that answer is elaborate enough.

I was able to reproduce when I expanded the notification window. I don't believe we account for larger notification window sizes. Again, I was not able to reproduce with OP's description. If what I found seems identifies OP's issue, I'll edit the title. One way to see OP is if you can reduce the size of your window until everything aligns properly.

@tmashuang I'm not entirely sure what you mean, this just happens when its in fullscreen for me. Like on the mac when the window is then a separate desktop pane?

[bdresser]

I think it's the same root cause - when the notification window is huge, the UI gets jumbled. Happens if you're either in a full-screen browser or if you stretch the notification window.

Thanks for reporting - for now you can workaround by using non-fullscreen, yeah?

Is there any workaround as the service provider?
something like forcing popup to open in non-full screen?

I'm getting the same error. I can reproduce it consistently if my browser is in full screen. Works fine if I'm not using full screen though.

Browser details:

OS: MacOS
Browser: Firefox 62.0.3 (64-bit)
MetaMask Version: 4.16.0
