Posted · ubuntu linux, nvidia card: menu entries garbled after resume from suspend

When resuming my ubuntu 22 machine with an nvidia graphics card, 2 monitors from suspend, I always find the display garbled:

 

  • most menu entries and controls are invisible, but can be selected
  • main area is scrambled, restores after moving

 

Here are some screens:

Is there something I can so - or should I file a bug?

 

Cheers,

Wolf

    Some more specifics could be helpful:

    1. What version of Ubuntu? You say 22 but there's 22.04 and 22.10.
    2. What GPU?
    3. Are you using the Nvidia proprietary drivers or just Nouveau?
    4. What version of whichever drivers?
    5. Are you running in X or Wayland?
    6. What version of Cura?
    7. Did you get Cura as a regular package, a Snap, or download the AppImage?
    8. Have you tested any other programs that use Qt? A whole bunch of them exist but the easiest way to find one is probably just to run something that comes as part of KDE (which uses Qt natively)

    I don't usually suspend my computer (just turn it off), but I have noticed (been using my Linux install a bit more lately) when loading Cura, graphical glitches like the ones you demonstrated, but they disappear by the time the interface fully loads. Could be related to your problem but I have no idea why it's happening, if I figure anything out I'll make sure to update you.

     

    To answer my own questions:

    Running openSUSE Tumbleweed fully updated, a 1080ti, proprietary drivers 535.113.01, X (because maybe one of these days Nvidia might actually make some drivers that support Wayland), 5.4 as an AppImage, and I'm using KDE, so using Qt all the damn time and haven't seen anything like it in anything else.

    Thanks for your care. I was not very specific as these troubles have been here for years on different versions.

     

    • What version of Ubuntu? You say 22 but there's 22.04 and 22.10.

    Roughly since ubuntu 16; now I'm at 22.04

    • What GPU?

    Various NVidia ones, at present it's a GeForce GT 630 Rev. 2

    • Are you using the Nvidia proprietary drivers or just Nouveau?

    Now the proprietary one.

    • What version of whichever drivers?

    nvidia package v 4.70

    • Are you running in X or Wayland?

    X11

    • What version of Cura?

    I started with something like 3.xx years ago, now at 4.11.

    • Did you get Cura as a regular package, a Snap, or download the AppImage?

    Former times a regular package, now AppImages. Both had the same problem.

    • Have you tested any other programs that use Qt? A whole bunch of them exist but the easiest way to find one is probably just to run something that comes as part of KDE (which uses Qt natively)

    Actually, Freecad often presents a garbled main window after resume as well, but that quickly disappears, controls in Freecad never are affected. Otherwise, CURA is the only one with this problem.
