This looks like a GTK bug. It affects all popovers, and only happens when both windows are on XWayland.

First, none of these windows are on xwayland--I mistyped there and meant to say "X, not Wayland."

I'm using dozens of other GTK applications with popovers without this issue. This seems unique to your application. What version of GTK are you using?

It doesn't just affect other windows. It affects the Gnome UI, as well.

I'm using GTK 4.8.3. I can reproduce the same bug with Dino and Nautilus on both X11 and XWayland.

The only application I can replicate this bug in is Nautilus (43.2), so if it's a GTK bug it seems to be pretty version dependent or there's something common in how it's being caused. I couldn't get current Dino (0.3.1) to do this.

I went through the Wikipedia list of GTK applications and selected 10 randomly and couldn't find another where I had this issue.

I think this might be specific to GTK 4. I can reproduce the bug with Dino 0.4.0 (they switched to GTK4 on this version), but not with Dino 0.3.1.

why would you use xwayland? Is this reproducible on Wayland? It is a Wayland native player, isnt it?
