1268394 - [Linux] [Developer Edition] About dialog has a different styling in comparison with other platforms

Status: RESOLVED WONTFIX

(DevTools :: General, defect, P3)

Description

[Andrei Vaida [:avaida]]

Attachment: screenshot

[Affected versions]:
- 47.0a2
- 48.0a2

[Affected platforms]:
- Ubuntu 12.04 LTS (x86)
- Ubuntu 14.04 LTS (x64)
- Ubuntu 16.04 LTS (x64)

[Steps to reproduce]:
1. Launch Firefox Developer Edition.
2. Click menu [≡] → Open Help Menu (?) → About Firefox.
3. Check the overall UI of the dialog - text styling, window background, padding, margins, etc.

[Expected result]:
- The window background as well as the text and images available in it are displayed properly.

[Actual result]:
- The dialog window is larger, possibly because of the way the text is wrapped.
- The "Want to help? Make a donation or get involved!" text is displayed lower than expected, with a flat blue background.
- The footer of the window has a black background, likely because it has a lower opacity and there's no color behind it.

[Regression range]:
- mozilla-aurora

- I'm aware that this range is not very helpful, but unfortunately this is the best I could do through mozregression.

[Additional notes]:
- This bug is _not_ reproducible with Nightly 49.0a1, Nightly 48.01, Beta 47.0b1. As far as I can tell, this is only happening on Aurora/Developer Edition builds.

This seems unlikely to be a widget bug.

I suspect the issue is just that the font is larger than other platforms, and perhaps the top image ("Firefox developer edition") is taller. The end result being the total height of the text + header image is taller than the background image size.

Joe, status for 48?

Comment 3

[Joe Walker [:jwalker]]

Deferring to jryans P3, so No.

Comment 4

[Brian Grinstead [:bgrins]]

Since this is a wontfix for 48, and 49 is unaffected, I'm going to close it out
