As can be seen in the following screenshot, the confirmation dialog has no shadow. Which is OK when the message window (its parent) is larger then it, but looks odd otherwise. Perhaps a slight shadow should always be added to these?

Nice catch! That would be awkward to ship!
@madsrh Not sure why you have tagged this gtk2-theme, evolution is a gtk3 app.
@CDrummond maybe because it looks very old school? ;D Just a little joke! :dancer:
Not sure we can do much with css here. I did fix another type of modaldialog today (so no wasted time :D)


but this one seems different. Its root is called dialog only, but it's not THE window, but a child of it, so I cannot get control of the whole window decoration

as you can see I can add a border, but the box-shadow does nothing since it is not the main/root widget

Yeah, adding a border here might be the best that can be done. Ambiance has no shadow, or border, and Adwaita has no shadow.
I haven't thought about adding a border, I'll check the effect later
Hi @clobrano @CDrummond
See this thread here https://github.com/horst3180/arc-theme/issues/8
Maybe you'll get an idea how to go about it.
Unfortunately what suggested in the thread mentioned by @Paz-it is what I did for modal-dialog, but did not work for dialog. However, I just observed the following:
This is "normal" dialog window

This is the same window after a Xorg restart (ALT-r)

it looks like something is wrong here
EDIT: instead, the modal-dialog is exactly the same in both cases, this is because it actually lacks of the shadow definition, but I can fix that in a next PR
@clobrano ... Maybe?
messagedialog.csd decoration {
@clobrano is there any relation to the "big" gtk dialogue change that was made several months ago? Or is it a gtk2 dialogue?
@Paz-it thank you, but that is for message dialog, which as said is fixable. message-dialog and dialog are different things
@Feichtmeier they are both gtk3 dialogs. I am using gtk3-demo from gtk-3-example package that shows also the source code of the example
@Feichtmeier gave me an idea, can it be Gnome-shell related dialog? :thinking: ...
@Paz-it no. I think it's also fixed with that PR :D
The dialog comes from the window, so no shell. I am going to ask upstream if there is something they can do about this gtk-dialog
How can this be closed? Dialog as shown in original message still does not have a shadow.
To recreate:
@CDrummond this has been closed automatically when PR has been merged, but if you go through the messages I said I will ask upstream why restarting the shell draws the shadows below the window.
My understanding is that if it was a communitheme issue, redraw should not change anything
@clobrano fair point! Sorry, I should have read the PR more closely :-( And I can confirm restarting the shell does produce a shadow.
