Thick black window border around popup windows and right click menus.

[nikolaof]

Describe the bug
The following behavior suddenly appeared at two apps that I'm running through xpra (vscode and planify).
What happens is when I right click somewhere or a pop up window opens there is a thick black border on it (see attached image).

System Information (please complete the following information):

• Server OS: Arch linux
• Client OS: Arch linux
• Xpra Server Version: 6.1.3
• Xpra Client Version: 6.1.3

Additional context

What app can I test with?
This looks like an xshape issue (#501).

Is this a wayland DE? Does it support compositing?
I don't think we support the shape on other platforms than X11:

xpra/xpra/client/gtk3/window_base.py

Lines 1256 to 1259 in 57777ed

	def set_shape(self, shape) -> None:
	shapelog("set_shape(%s)", shape)
	if not HAS_X11_BINDINGS or not XSHAPE:
	return

I'm using X11 and so far I saw this on visual studio code insiders and planify applications

[totaam]

Any real open-source applications?

[nikolaof]

Isn't planify real open source application? It comes with a GPL-3.0 license.

I tested it with obsidian as well and got the same behavior to some right clicks.
Zotero on the other hand does not make it.

None of these apps are available in the default Fedora repos which makes it harder for me to debug.

[nikolaof]

Can you tell me an app that you can use?

[totaam]

Any application in the Fedora repositories - there are thousands of them.

[nikolaof]

So it is happening on Visual Studio code. Can you test it on this app?

[totaam]

No vscode is not the Fedora repos.

Maybe your window manager handle transparent windows?

I'm using i3 on X11. I installed picom and the difference is that it shows this thick area but now kind of transparent.

[totaam]

but now kind of transparent.

Can you include a screenshot with and without picom?

[nikolaof]

Without picom is the image in the initial post and here is the one with picom

This popup menu looks an awful lot like the one the shows up when you click on gedit's pancake button.
Can you run gedit to see if you get the same problem?

[nikolaof]

Nope. this is not the case with the gedit. I tried it and it works fine with and without picom.
I start think that the issue is only related with apps that are written using electron framework

That's quite possible, likely even: #4365 (comment)
