Yaru: White line under menu bar in Sublime Text 3

[chrisjbillington]

Using the edge snap, I see a white line underneath the menu bar in Sublime Text 3. It was not there in a previous version of the communitheme gtk theme. However, I had not updated in several months (was formerly installed via the ppa and I had removed the ppa from sofware sources), so I don't have a guess for how long ago this was introduced. I do not see the white line under other menu bars, for example gnome-terminal. I think Sublime Text 3 may be using GTK 2, but I am unsure. So that may explain why I don't see it elsewhere.

Here is a screenshot:

Thanks for reporting this. The problem is due to a white GTK2 assets, but before changing it, we should double check whether it is not necessary to have it white in other applications

[clobrano]

After checking, I believe this can't be fixed on our side.
SublimeText3 is the only GTK2 I know that uses a "line" asset as bottom border for the menubar, this asset has been changed in July to a brighter color, this is why you saw the change only recently.

Just to explain why I wouldn't change it, this is our test application if "line" was darker

instead of

simply put, "line" should not be used as border for a dark element

[chrisjbillington]

Fair enough. I suppose I'll report the bug to Sublime instead then.

@clobrano, IMHO, The white line is there because we don't have dark gtk2 yet.

[clobrano]

@Paz-it, I have it :) and doesn't fix it. Sublime doesn't prefer dark variant a a used the bright line

[clobrano]

Fair enough. I suppose I'll report the bug to Sublime instead then.

that's a good idea, thank you.
