Rectangular grey area around title bar

[Louis]

After updating to the new GTK3 version of Terminator there's a rectangular grey area around title bar.

I've looked trough settings but there seems to be no way to disable this.

Louis, are you using a packaged 1.90 or the gtk3 branch head? I've seen that exact effect due to theming when trying to fix the transparent backgrounds (https://bugs.launchpad.net/terminator/+bug/1599453). I fixed all the bad interactions I could find in the head of gtk3, but they are not yet in an official release yet. Can you take a look? It might also help to know what theme you are running.

I'm using Arch Linux with terminator gtk3 branch at version r1702, Gnome shell build r1702 and the vertex theme version 20161009. If I switch to an another theme like Adwaita the issue is still present.

[Stephen Boddy (stephen-j-boddy)]

Then that's very strange. I fixed this exact symptom for Adwaita already in:
https://bugs.launchpad.net/terminator/+bug/1599453
If you search down through the comments you will see me mention the grey box around the title bar under Adwaita. I spent quite a bit of time finding and fixing various transparent rendering issues, culminating in the merge of a decent chunk of work:
http://bazaar.launchpad.net/~gnome-terminator/terminator/gtk3/revision/1672
Specifically for this issue the fix was in terminatorlib/terminator.py, lines 417-424.
That change fixed the rectangle for myself and the OP on 3.18. It makes no sense that it doesn't work for you, as it is a cross theme fix, and you are on a newer gtk. The best I can suggest is that you use:
GTK_DEBUG=interactive terminator -u
and see if you can find exactly what element in the hierarchy is introducing the grey box for you. Otherwise it's a case of randomly making changes in a probably futile attempt to fix it.

Louis, can you check with an up-to-date branch with rev. 1714. That rev is merging in a change for GTK 3.20+ where CSS selectors now have to use nodes. One of the changes needed in this rev would explain why you still experience an issue I already fixed. (Note that, yet again, the breakage is because Gnome like to change stuff for the hell of it.)

This issue has been resolved in branch r1714. Thanks!
