The dock is shown in front of full screen windows since 19.10

Thank you for your bug report. Do you use an xorg or wayland session? Is that happening with any windows? Can you try with firefox fullscreen to see if it has the same issue?

[FransSchreuder (fransschreuder1)]

Dear Sebastien Bacher, Thanks for the quick follow-up.
I tried both xorg and Wayland, they have the same behaviour.
Firefox goes nicely in front of the dock, it seems to be only X2go that goes behind the dock

Status changed to 'Confirmed' because the bug affects multiple users.

[lotuspsychje (lotuspsychje)]

20.04 development branch on kernel 5.3.0-18-generic and intel 620 UHD graphics

Also affected with Xscreensaver, the dock stays visible

[user user (user45671)]

I have the same issue. It forced me to revert back to 19.04 from latest ver. of 19.10.

It was already a problem since week prior to release of 19.10 (when I first tried).

19.10 latest ver on Intel Graphics 530.
This bug is impacting on: modesetting driver xorg as well as intel driver xorg. I also tried Wayland to same result.

This is impacting a fullscreen video game I'm playing in OpenGL.

Also just want to note: it feels like since the Dock is showing in fullscreen (it isn't really fullscreen). There is a huge amount of CPU usage + input lag. Switching back to 19.04 was like night and day. OpenGL 64-bit game runs fast and good on old release.

On new one- 19.10 the dock is not possible to hide and it doesn't feel like true fullscreen (huge input lag with 144 Hz monitor).

(Apologies if this is in the wrong place to report bugs pertaining to dock showing in full in other applications - OpenGL games etc), it's my first bug report.

[user user (user45671)]

What do I need to do to have this looked at more closely? I can send a screenshot of the game in question. The input lag is so absurdly high with 19.10 and this bug among other things makes 19.10 feel like a huge regression for me. I am using 19.04 now and everything runs faster and I don't get this bug where the dock is infront of the the fullscreen application. I tried wayland, with modesetting, without modesetting - nothing works.

[Sebastien Bacher (seb128)]

@user user, could you open a new bug report using 'ubuntu-bug gnome-shell'? Having the system info would be useful, especially the video card/driver in use. Also what game are you trying and what input device do you use?

[user user (user45671)]

@seb128
Sebastien, are you referring to this page?
https://bugs.launchpad.net/ubuntu/+source/gnome-shell

The specific issue is that the "dock" is exposed and it doesn't feel fullscreen.

System info: Intel Integrated Graphics 530 (NO GPU, just processor)
I've tried default 19.10 input device modesetting as well as specifying with an intel-20 xorg config to use Device driver "intel" (rather than modesetting)

Sebastien this is what I'm trying to launch, it uses OpenGL and is coded in C. It always worked fine launching in fullscreen.

[Sebastien Bacher (seb128)]

Thanks for the reply, still could you use the ubuntu-bug command to report a bug, the journal log could have useful information? Also what is 'his' in 'this is what I'm trying to launch'? Could you give a concrete example, it might make testing easier for others

@ sebastien #11

I created a gnome-shell bug for this as im also experience the bug, but only with
Xscreensaver, see bug:

xscreensaver (glmatrix) was active (two displays) however the Ubuntu DOCK was fully visible on my primary display.

[lotuspsychje (lotuspsychje)]

seems to be fixed for me with xscreensaver shows fullscreen again
and does not fight with the dock anymore on 19/4/2020
