Description Leon Fauster 2020-03-01 22:55:59 UTC

Description of problem:

Following are observed under RHEL8, GNOME+WAYLAND session:
Drag and drop files under nautilus have huge delays. See
https://gitlab.gnome.org/GNOME/gtk/issues/211


Version-Release number of selected component (if applicable):

$ rpm -qa |egrep "^gtk3|^nautilus"
nautilus-3.28.1-10.el8.x86_64
gtk3-3.22.30-4.el8.x86_64


How reproducible:
Open two nautilus windows and drag and drop back and forth until ...


Actual results:
Huge interaction delays in UI (files moved very delayed)


Expected results:
drop without delay

Comment 1 Ondrej Holy 2020-03-02 12:58:21 UTC

As per the linked merge request, this seems to be clearly gtk issue, thus changing the component.

Comment 2 Tomas Popela 2020-03-16 09:40:28 UTC

Adding Carlos as an assignee as he has done the upstream patch. Also setting ITR to 8.3.

Comment 3 Leon Fauster 2020-03-20 14:37:08 UTC

For verification I applied the patch https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/1057.patch into the current gtk3-3.22.30-4 EL8.1 version. The rebuild shows good results. No delays while DnD and so far no regressions.

Comment 4 Leon Fauster 2020-05-11 12:17:43 UTC

I consider this a blocker bug (usage context: workstation with default config (wayland)). Any status update?

Comment 5 Tomas Pelka 2020-05-11 16:58:42 UTC

Honestly I was not able to reproduce.

Can you see anything in journal when drag-n-drop?

Comment 6 Leon Fauster 2020-06-24 13:52:07 UTC

Current setup (Version 8.2):

$ rpm -qa |egrep '^mutter|^gtk|^nauti'|sort

While trying to drag two selected PDF files into a new created directory. Two times, both with delays around 10-25 seconds.

Comment 7 Leon Fauster 2020-06-24 14:03:51 UTC

Maybe relevant. Because I noticed that the "fall down" selection menu (like in evolution recipients with multiple adresses) does not appears on one screen (main), just on the second screen? (Maybe an issue for a separate bugzilla entry).

This is a dual screen setup (2x HDMI). Albeit the DND issue happens while using the one or other screen.

Do not known if xdpyinfo is the right tool to collect information (Wayland display manager is used).
