Screencast: the video freezes when the freeze happens (time stands still at the top)

Description of problem:
When moving the mouse over the time slider of vlc when playing a file, the system freezes for the duration of the media file.
Mouse does not move, keyboard does nothing, CTRL+ALT+Fn does not work.

Version-Release number of selected component (if applicable):
gnome-shell-3.24.2-1.fc26.src.rpm
vlc-3.0.0-0.29.git20170622.fc26.src.rpm (from rpmfusion-free)

How reproducible:
100%

Steps to Reproduce:
1. Open nautilus and browse to your media collection
2. Open a media file with VLC
3. Bring nautilus to the foreground (VLC in background)
4. Open another media file
5. Move your mouse pointer from above to below over the time slider of VLC

Actual results:
The system freezes.

Expected results:
No freeze please.

Additional info:
I could only reproduce this on Gnome on Wayland.
Not on Gnome on X.

Comment 1 maarten 2017-07-12 11:37:13 UTC
The freeze ends at the end of the media file.
Once gnome-session crashed at the end of the file.

Comment 2 maarten 2017-07-13 13:00:21 UTC
This freeze can be reproduced on a freshly installed VM.

- install fedora 26
- # dnf upgrade
- # dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
- # dnf install vlc
- Set VLC as default for Music and Video in 'All Settings'->'Details'->'Deault Applications'
- Download 2 audio files
- Close all windows & open nautilus & browse to folder containing audio
- Open 1 audio file, move vlc player to side next to nautils
- Bring nautilus to foreground
- open another audio file
- move mouse pointer over time slider
* freeze happens *

Hi maarten.  Do you still see this happening after updating VLC.  I had the same issue on F25, but it disappeared with VLC fixes.

Comment 4 maarten 2017-09-25 15:27:49 UTC
Hey, this is fixed in the current rpmfusion repositories. See https://bugzilla.rpmfusion.org/show_bug.cgi?id=4596

Comment 5 Sebastian 2018-07-24 12:12:19 UTC
Can reproduce this in Fedora 28 and with VLC 3.0.3.

Comment 6 maarten 2018-07-24 12:22:50 UTC
I have re-opened the issue on the rpmfusion bug tracker. https://bugzilla.rpmfusion.org/show_bug.cgi?id=4596#c7

Thanks, maarten, for creating this bug!  The fix you cited in comment #4 has landed in RPMFusion-testing's vlc-3.0.4-1.fc28 .

I confirm that I can no longer duplicate the problem under Wayland on Fedora 28 after upating to this version:

dnf --enablerepo=rpmfusion-free-updates-testing update vlc

Comment 8 Sebastian 2018-09-12 17:54:38 UTC
I am not able to reproduce the problem anymore. Thank you!

Comment 9 maarten 2018-09-12 22:55:03 UTC
@Jargon Scott: The patch mentioned in #4 was for a freeze problem with vlc last year.
The actual patch fixing the freeze is http://git.videolan.org/?p=vlc.git;a=commit;h=6579a36c56ed30b72de584bf0e8cf21af1a90cf7

Let's hope this problem will not return,
because the problem is still present on wayland:
