Strange grey border appeared on top and right edges of screen when using Numix GTK+ theme

[Wise Melon]

I don't know how long it's been there for as it's hard to notice, but I noticed it a few days ago, there seems to be a grey border on the top and right edges of my screen in the same kind of colour as the login/locked screen for GNOME. As can be seen in the attached screenshot (I have edited the image to replace all but the bits I want to point out with white):

As I have stated in my comments, this issue only seems to be present when setting Numix as my GTK+ theme. No other themes seem to have the issue. Though I cannot currently reproduce it in my 16.10 VM, so it's possible that it's an issue with the packages in gnome3-staging.

Hi, I can't make much out of your screenshot. It just looks like a big white rectangle to me.

Could you run this command so we can at least see what your nautilus settings are?

Do you still have the problem if you don't have nautilus draw desktop icons?

If you have Unity installed, could you check whether you experience it on Unity too?

Virtually all of GNOME 3.20 is in Ubuntu 16.10 (development) so you're welcome to try out an alpha image to see if you can reproduce these bugs there.

Oh, right, I see... If you download it and open it in something like GIMP you should be able to see what I mean, but I have also attached a non-edited screenshot in hope that you can see what I mean better (zoom in on the top right hand corner).

If I disable "Icons on Desktop" in the gnome-tweak-tool the issue goes away, but comes back upon re-enabling them. I do not have any other Desktop Environments installed. I also understand that there are problems with having multiple DEs on Ubuntu so I'm not sure about installing it...

I do not currently have the facilities to run a VM, however I will soon have this sorted out and will test the image.

I have tested in an up-to-date 16.10 VM and I can't reproduce the issue. However I only booted into it and checked, I didn't actually try to reproduce my setup at all, so I will also test soon if it is theme related or anything like that.

[Wise Melon (wise-melon-deactivatedaccount)]

I have just tested on my host 16.04 system and it appears as though the issue goes away when I switch from back from Numix to Adwaita in terms of my GTK+ theme. However when I switch back to Numix within a few seconds the issue comes back, so it seems only to be present when Numix is set.

I am unable to reproduce it in the 16.10 VM, though perhaps this is an issue specific to the gnome3-staging PPA?

I removed the nautilus (Ubuntu) task since technically this does not appear to affect the version of Nautilus in the archives. The Ubuntu Desktop team has enough bugs to deal with that eliminating PPA-only issues is a help to them.

The GNOME 3 Staging PPA for Ubuntu 16.04 LTS should have basically the same nautilus as Ubuntu 16.10 "yakkety". The gtk+3.0 package in the PPA is a little newer because the GTK update in yakkety got stuck in the -proposed queue.

With some more testing I have found that the issue takes a few seconds (maybe between 3 and 5, but reasonably long) to appear when I first log in (I have not yet tested with the lock screen). I have also noticed that it is not present in the Activities Overview and takes a few moments to reappear when I exit the AO.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.
User no longer uses Launchpad so cannot ask if issue is still
apparent in a current Ubuntu release. There are no similar
outstanding bugs reported by other users.
Closing as "Invalid".
