pdf-tools' arrow issue on X about emacs

[masm11]

while in Wayland the arrow does not have a shadow background.

Whether a window has a shadow is depend on the environment even if on X.
I think it is not important.

the arrow stays there after alt-tab

What does your alt-tab do?

I personally don't think this is a bug, as said in #51, I think it is better this way. But I do not know if this is related to the desktop environment/emacs/X vs Wayland/pdf-tools or if the developer had a clear intention.

What does your alt-tab do?

Switches to another window, in this case to a nautilus one. I will test later if moving the window also creates this behaviour.

@A6GibKm

Switches to another window,

Only switching focus? Or the emacs window disappears?

I do not know exactly the difference, but I think it switches focus. Let me be more precise on ways of reproducing this on GNOME and X11. This was done on Fedora Silverblue 33 which uses GNOME 3.38, but I am sure the only relevant bit is GNOME+Xorg.

1. Open a latex file and it correspondent pdf-tools buffer and a folder under nautilus, press alt-tab to switch to nautilus and the arrow will be still be there, note that the arrow dissapears after ~3s so this has to be done quickly.

2. Under the same setting as before, instead of using alt-tab you can have both windows minimized and after the arrow appears, just drag the folder on top of the buffer, and the arrow will still appear.

3. Under the same setting, just make the arrow appear and move the Emacs windows, the arrow won't follow the window.

How to drag it while both of nautilus and emacs windows are minimized?
You mean dragging from desktop?

[A6GibKm]

My bad, I meant "while both windows are not maximized" so you are able to move one window on top of the other by dragging.

I would like to screen record this, but I only know how to screenrecord under wayland.

EDIT: Actually...

Gnome has a built in screen recorder which should work for this.

The Silverblue base image does not come with it as far as I know. But the above edit has a imgur gif with the recording.

EDIT: Actually CTRL+Alt+Shift+R starts/stops screenrecording.

[masm11]

thank you for the screen record. I understood.

ok.

On combination of X-build and GNOME(Xorg),
the arrows seem to disappear when some of mouse events occur.
I'll try to make pgtk emacs the same behavior.
Please wait for a while.

[A6GibKm]

Are you sure it disappears on certain mouse events? It gives that impression but I am sure it is on a short timer.

[masm11]

I am sure it is on a short timer.

I didn't think the possibility of a shorter timer. thanks.

@A6GibKm Try #59. It is fixed in some cases.

[A6GibKm]

I am testing right now and I am not sure what changed. The arrow now disappears when passing the mouse over the title bar of Emacs (I am not sure any more if this is part of the intended behaviour) and it does not follow the window.

To be honest X is a pain and I don't use it at all, it might be the case that the arrow does not work at all on x11 on upstream emacs either.

It is also the behavior of X-build.

it does not follow the window.

On X-build, the arrow disappears when starting moving the window.
But on pgtk, I can't get any events on starting moving the window. Instead, I get a event on ending moving the window. That is why the arrow stays while moving the window and disappears when ending moving the window.
