I can confirm in Signal 0.40.0 on Chromium 58.0.3029.110 (Linux).

Hey there - sorry about the inconvenience! I expect that this is due to the same root cause as #1205, and is similarly fixed by #1202.

If you get a chance, we'd love some help verifying that this behavior is fixed. It's pretty simple to check out the repo and then load the unpacked extension into Chrome: https://github.com/WhisperSystems/Signal-Desktop/blob/master/CONTRIBUTING.md#installation. If not, we'll have an official update with the fix out soon.

I tested on a non-HiDPI Linux box and this bug appears resolved by the build.

I can confirm that, not reproducible on the newest build, anymore.

Well, I'll go ahead and close the issue then. @scottnonnenberg, when will this be released?

Tomorrow evening is the current plan!
