Unable to activate Modal/Dialog Windows shadows

[jEsuSdA]

Hi!

I'm trying to add shadows to several modal/dialog windows for GTK3 apps and I can't.
What I'm doing wrong?
Is there any "force shadow" option for compton.conf?
Could you help me?

Platform: Debian Testing 64bits (Compton installed from official repos)

GPU, drivers, and screen setup: Intel GPU with two monitors and glx backend for compton

Compton version: 0.1~beta2+20150922-1 from the Debian official repository.

Compton configuration:

Thank you!

I noticed that removing the line

"! name~=''",

The shadow appears in modal/dialog windows!!! yeah!

But... Could this have unexpected consecuences?
Do you know?

I can confirm that the shadow in modal windows does not appears in all case.

e.g. Firefox-esr modal "save file" has no shadow.

News:

The exclude condition:

"class_g = 'Firefox-esr' && argb",

Disables shadows under popup menus but ALSO under it's modal windows.

Disabling this condition the shadows appears under the Firefox modal windows, but the popup menus looks ugly.

Is there any way to disable shadows ONLY in popup menu but modal windows?

And finally I found a perfect solution:

1. Remove the "! name~=''", line

2. Remove the "class_g = 'Firefox' && argb", lines

3. Add these lines:

   "class_g = 'Firefox-esr' && class_i = 'Popup' && argb",
   "class_g = 'Firefox' && class_i = 'Popup' && argb",
   "class_g = 'Thunderbird' && class_i = 'Popup' && argb",

You'll have shadows on Firefox/Thunderbird modal and drop downs and popup but the "special" popup from Firefox/Thunderbird do not have any shadow.

Great!!!
