Gnome (on Xorg) dishonours customized cursor theme while hovering the desktop and the windows decorations

[fcole90]

If I use lightdm to load GNOME Shell, I encounter a very weird bug: if I move the cursor to hover the desktop, the cursor theme becomes DMZ White, but if I move the cursor over the GNOME panel or over any open window, it returns back to the custom theme set by me.

I can experience this bug only when using lightdm, if I use gdm3 I always have the same cursor.

Note that I'm not on Wayland and that I have nautilus folders on my desktop.

I made a screencast of this behaviour. I rescaled it to keep it in a limited size

After making the screencast something fixed this behaviour, at least for this session..

It appears the bug does not exist in 17.10. So this is either Fix Released post-16.04, or some problem specific to your custom theme. Please help us to figure out which by:

1. Testing Ubuntu 17.10 or 17.04; and
2. Testing the standard Ambiance/Radiance themes.

[Daniel van Vugt (vanvugt)]

Sorry. Confirmed on artful. You just have to log in using the GNOME session (not GNOME on Wayland). So this is a Xorg-specific bug, which still exists.

Thank you for reporting this bug to Ubuntu.
Ubuntu 17.10 (artful) reached end-of-life on July 19, 2018.

We appreciate that this bug may be old and you might not be interested in discussing it any more. But if you are then please upgrade to the latest Ubuntu version and re-test. If you then find the bug is still present in the newer Ubuntu version, please add a comment here telling us which new version it is in and change the bug status to Confirmed.
