panel transparency not working when gtk.css is present

Hi,

I have a ~/.config/gtk-3.0/gtk.css containing the following code to colour the workspace switcher (buttons):

#pager-4 button { background-color: #B35A57; }
#pager-4 button:checked { background-color: #4B7946; }
#pager-4 button:hover { background-color: #406398; }

looks pretty good. BUT, if this gtk.css exists transparency of the panel is not working anymore.

When I rename/delete the gtk.css transparency works fine again.

Do I need any additional entries in the gtk.css to make transparency work...

Thanks a lot

if the code gets deleted, thus an empty gtk.css exists, this behaviour is still present

That code shouldn't have any impact on the transparency of the panel. Have you tried restarting the panel:

xfce4-panel -r

yes, panel restarted several times
everytime I changed the gtk.css

Which distro and which version of Xfce are you using?

Can you run xfce4-panel in debug mode and post back the output?

xfce4-panel -q
PANEL_DEBUG=1 xfce4-panel

I can't replicate this issue on Arch Linux using Xfce 4.16,

ToZ,
thanks a lot for your efforts - highly appreciate :-)

I use debian 11 and xfce 4.16. The only thing what came in mind was, that I removed gnome completely and installed xfce (never regretted...;-) Proably I missed something...

But, the problem got solved by a behaviour which I would describe as a bit creepy...

I set the transparency to 0 (for enter and leave panel). Nothing happend = no transparancy.
Then I made a screenshot (shift+print) to cast a picture how it looks.
I selected an appropriate area, panel included of course. I got a terrible screen greasing (pointer and coordinates) on the panel.

Then, in some kind of "panic attack", I restarted the panel and now it works and looks fine as it should....

I promise, I had restarted the panel several times before...with no result.

Now I'm pretty happy with my deskop ;-)

Probably XFCE has some kind of self-healing power...

Just wanted to say that changing background transparency is different in 4.16. The enter/leave opacity changes the visibility of both the background transparency and the icons. To change just the background, you should follow these instructions.
