Description Ken Dreyer 2015-04-08 04:03:59 UTC

Description of problem:
The icons in my notification area (for example, the icon for krb5-auth-dialog, or for NetworkManager) have a black background. In Fedora 20 these icons' backgrounds were transparent. In Fedora 22, each icon has an individual black box.

Version-Release number of selected component (if applicable):
xfce4-panel-4.12.0-3.fc22.x86_64

How reproducible:
I upgraded two separate computers to Fedora 22. Both are running XFCE, and both displayed the same issue.

Steps to Reproduce:
1. Create a XFCE panel
2. Add a "Notification Area" element to the panel
3. Examine the icons that are present in the Notification Area

Actual results:
In Fedora 22, each icon has an individual black box.

Expected results:
Each icon should have a transparent background, as in Fedora 20.

Not reproducible here in my f22 xfce4.12 kvm. At least not for NetworkManager. 

Ken,
- what theme do you use? I use Adwaita theme with Fedora icons.
- Maybe try with some other themes and look if transparency comes back.
- What graphics card and driver do you have, is composition enabled?
- Is there any special configuration of the panel (width etc.)?

If that all does not help, this is maybe another gtk3 regression, as already seen with bug #1208183.

I seem to recall nm-applet showing the described behavior sometime back, but I thought that was fixed ... weird!

I guess I am echoing Raphael's question here, is this a specific theme or all themes that you tried?

I'm using a custom theme (it's "Mist", but I've tweaked the colors to be a little brighter).

When I switch to the stock Adwaita theme, I see the same issue.

> - What graphics card and driver do you have, is composition enabled?

I'm using the onboard graphics in my laptops. On my first laptop, Xorg.0.log says it is "Intel(R) Iris(TM) Pro Graphics 5200". On my second laptop (MacBook Pro), it is "Intel(R) Iris(TM) Graphics 5100".

When I toggle composition on, the problem disappears. I can kill the krb5-auth-dialog process and restart it, and the icon shows up as expected (with a transparent background).

When I turn compositing back off, something weird happens: the krb5-auth-dialog icon gets displayed *on top* of a second NetworkManager icon. When I  kill/restart krb5-auth-dialog at that point, the double-icons thing doesn't occur, but the krb5-auth-dialog icon shows up with a black background again.

This happens on both computers. So it seems this issue is restricted to scenarios where compositing is turned off.

> - Is there any special configuration of the panel (width etc.)?

Not that I know of. It's the same panel configuration I've used for years: horizontal mode, row size 28, one row, length 100%, snapped to the bottom of my screen.

Is this still an issue? I have not seen this in quite a while now ..

Comment 5 Ken Dreyer 2016-01-17 00:48:49 UTC

Same here, I've not seen it for a while.

Comment 6 Mukundan Ragavan 2016-01-21 00:20:22 UTC

Glad to hear that. Please reopen if you see this again.
