Leap 15.5 black windows

I’d been using Leap 15.4 fine for a year but after upgrading to Leap 15.5, windows sometimes display black boxes instead of their content.
Here’s what led to this:
I upgraded from 15.4 to 15.5. After that, I had to reinstall Nvidia drivers because system GUI didn’t load. After reinstallation, it started working again. Currently I have -G05 drivers from Nvidia repository (tried installing -G06, no difference)
Black windows don’t apper immediately after booting up. They appear only after some time(a day, or two).
Those black boxes are also apply to context menus. alt-tab menu, etc…
My system:
Operating System: openSUSE Leap 15.5
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 5.14.21-150500.53-default (64-bit)
Graphics Platform: X11
Memory: 15,6 GiB of RAM
Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2

How can I fix that?

Does it work when you drag the window towards the top screen a little faster?

Have you tried to use the nouveau?

I have had also Problems with Nvidia driver after a while when opening a submenu by rightclicking such as “save as” in dolphin/krusader or in firefdx “open in new tab” or something else.

Its gone since I use nouveau.
My card:

inxi -G
  Device-1: NVIDIA GP106 [GeForce GTX 1060 6GB] driver: nouveau v: kernel
  Device-2: WaveRider USB Live camera type: USB
    driver: snd-usb-audio,uvcvideo
  Display: x11 server: X.Org v: with: Xwayland v: 22.1.5 driver: X:
    loaded: modesetting unloaded: fbdev,vesa dri: nouveau gpu: nouveau
    resolution: 1: 1920x1080~60Hz 2: 1920x1080~60Hz
  API: OpenGL v: 4.3 Mesa 22.3.5 renderer: NV136

The only action that might (sometimes) restore displaying of a window content is window minimising/maximising. Any other action with a window don’t produce any effect.

I remember using Nouveau some time ago before that problem and I think its performance was too low for gaming as I play games sometimes. I’d prefer using Nvidia drivers for performance.

So you have to open an bugreport.


It looks as if, somehow, no idea how but, you seem to have selected a “Darkscheme, somehow …

  • BTW: from the image you’ve posted it seems that, you’re using the KDE Plasma Desktop.

  • Please, check the following in your KDE Plasma System Settings –
    Appearance” → “Global Theme” –– possibly, it’s set to “Breeze Dark
    Possibly – “Appearance” → “Plasma Style” is, possibly, set to “Oxygen” …
    Possibly – “Appearance” → “Colors” is, possibly, set to either “openSUSEdark” or “openSUSEdarkalternate” or, something else which is “Dark” …

Ditto for Firefox – “Addons and Themes” → the selected Theme …

There aren’t any issues for several hours after booting into system, so it’s not related to any theme/style preferences I have set.
Black boxes appear in light theme as well.

Hmmm –

This Leap 15.5 system:

Operating System: openSUSE Leap 15.5
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 5.14.21-150500.55.12-default (64-bit)
Graphics Platform: X11
Processors: 8 × AMD Ryzen 5 3400G with Radeon Vega Graphics
Memory: 29.3 GiB of RAM
Graphics Processor: AMD Radeon Vega 11 Graphics
Manufacturer: ASUS

Occasionally (less than once a week) what I was seeing, concerning only Mozilla Firefox and Web-Browsing, was either a blacked-out Firefox window or, not so often, a blacked-out Desktop.

  • The window or Desktop resumed to normal behaviour after a second or so of mouse movement.

I haven’t been plagued by this during this week (it’s now Friday) – possibly a patch has resolved the issue …

This was also the behavior on my system, but I went back to nouveau.

So as I said above:
open an bugreport.

Do you use a dark gtk Theme?

Can you switch to a brighter one?

Does that work?

I have “Breeze dark” as the global theme and also have “Breeze” selected under “Global theme” => “Application style” menu
Have already tried changing Breeze Dark to Breeze (light) but it didn’t change anything.

I think I need a little nudge before opening a bug report as I haven’t seen those black boxes for a couple of days, and I’m a bit lazy getting familiar with how bug reporting works, though they will certainly appear again, so it’s only a question of time.

I just noticed that after restarting Firefox, this bug seems to completely dissapear.
I don’t have any clue why.
