xfce4-panel transparent pixels?

inparsian · 2019-11-03 16:59:13

I use Manjaro 18.1.2 Juhraya, it has the Openbox window manager with the xfce4-panel (version 4.14.1).

I've noticed that most pixels on the top and bottom of the panel are transparent, while others are not, thus only 2% (30 pixels) of the panel are actually touching the very bottom of the screen.

Screenshot of problem (look closely at the top of the panel, the bottom does the same thing):

Is there any way to fix this? Thanks!

Hello and welcome.

Which appearance (GTK3) theme are you using and what size/height is the panel?
Does it happen with all themes or just this one?
What plugin is being used right at the left of your screenshot? Whiskermenu?

Also, do you have any content in ~/.config/gtk-3.0/gtk.css?

The height of the panel is 30px. It happens when I set the panel to a solid color, and yes It's whiskermenu. I do have content in the gtk.css file.

Can you post the contents of the gtk.css file?

Also post back the results of:

xfconf-query -c xsettings -p /Net/ThemeName

Vertex-Light

I can't replicate this on a Manjaro 18.1.2 VM. Did you get the Vertex-Light theme for the "vertex-theme" package in the repositories?

Also, try renaming the gtk.css file (to something like gtk.css.bak) and restarting the panel:

xfce4-panel -r

...to see if it makes a difference without the file in place.

Tried it, no difference.

ToZ · 2019-11-04 01:39:40

Hmmm. I just can't replicate this.

Can you try a few things:

1. Try another appearance theme - preferably Adwaita. Restart the panel (xfce4-panel -r) and see if it makes a difference.

2. Re-enable xfwm4 (xfwm4 --replace) and see if it makes a difference.

3. Create a test user and log in as that user. Change the theme to Vertex-Light, enable openbox, and restart the panel. Does the issue persist?

Edit: Are you using something like compton for compositing?

I use xcompmgr for compositing.

1. How do I change the appearance theme (sorry, i'm new to the xfce4-panel)?

2. Didn't help, issue persists.

3. Issue persists.

Settings Manager > Appearance > Style tab. Try with the "Adwaita" theme. Restart the panel to make sure.

Tried the Adwaita and Adapta-Nokto theme, issue still persisted.

I can't seem to replicate this problem. Same distro. Running openbox and xcompmgr. I'm not sure what to say.

Perhaps you can open a bug report and see if the developer has some ideas on what might be happening here.

Edit: Just want to confirm that the same thing happens when running just xfwm4 and with openbox and xcompmgr not running.

Where can I file a bug report, may I ask?
