Widget Layout Jumping when printing

[Manuel Barkhau]

While a print job is active, the layout in the printers panel becomes unusable. The dropdown for the gears icon is removed almost immediately after the click that opened it.

Thank you reporting this bug and make Ubuntu better!

Before filing bugs, could you update your system to latest and test this bug again please?

Something also went wrong with your screen record, could you make a new one and/or screenshot?

Maybe also attach your dmesg logs so volunteers can debug a better way.

Does the video not work for you? I've downloaded it again and playback works for me. Does playback not work for you, or what is the issue?

[lotuspsychje (lotuspsychje)]

Ok seems like your video is working now.

Did you update system to 5.0.0 -25 and test if the bug remains?
what about booting an older kernel, does this still happen?

[Manuel Barkhau (mbarkhau)]

I updated, rebooted and the issue persists:

> $ uname -a
> Linux mb-spectre 5.0.0-25-generic #26-Ubuntu SMP Thu Aug 1 12:04:58 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

[lotuspsychje (lotuspsychje)]

Can you upload your dmesg logs too please
and sudo lshw -C video could also be useful

did you try gnome3 vs gnome-flashback to see if your bug persists?

[Manuel Barkhau (mbarkhau)]

The issue exists both on gnome3, as well as gnome-flashback.

$ sudo lshw -C video

Could you report it upstream on https://gitlab.gnome.org/GNOME/gnome-control-center/issues ?

[Manuel Barkhau (mbarkhau)]

I reported it a while ago, doesn't seem like anybody is picking it up:

[Sebastien Bacher (seb128)]

Thanks, could you also add your 'journalctl -b 0' log after triggering the issue?
