Plasma-wayland session: when you open an image in Gwenview, it is transparent, that means that you just see other windows that are behind Gwenview. gwenview-20.08.2-1.fc33.x86_64 qdbus org.kde.KWin /KWin supportInformation ========================== Version ======= KWin version: 5.20.1 Qt Version: 5.15.1 Qt compile version: 5.15.1 XCB compile version: 1.13.1 Operation Mode: Xwayland Build Options ============= KWIN_BUILD_DECORATIONS: yes KWIN_BUILD_TABBOX: yes KWIN_BUILD_ACTIVITIES: yes HAVE_DRM: yes HAVE_GBM: yes HAVE_EGL_STREAMS: yes HAVE_X11_XCB: yes HAVE_EPOXY_GLX: yes HAVE_WAYLAND_EGL: yes X11 === Vendor: Fedora Project Vendor Release: 12009000 Protocol Version/Revision: 11/0 SHAPE: yes;

I have noticed that the same problem happens also with obs-studio-26.0.2-2.fc33.x86_64
Can you run Gwenview from the terminal as follows env WAYLAND_DEBUG=1 gwenview > log.txt 2>&1 and post the resulting output here? Make sure that the log output doesn't contain any sensitive data.
opengl rendering does not work on Wayland, see bug 403323
I can't confirm this issue on KDE Neon User Edition with a jpg or png file. Also checked compositor and it says I'm on OpenGL 2.0.

Are you using Kvantum or a 3rd-party widget theme?
(In reply to Nate Graham from comment #6) > Are you using Kvantum or a 3rd-party widget theme? I don't know what they are, but if you tell me how I can verify, I will check
If you don't know, you're probably not. :)
Can't reproduce. Can you take a screenshot / photo. Does it happen with all images
Created attachment 132878 [details] screenshot instead of showing the photo, it shows Libreoffice and my desktop wallpaper that are behind the Gwenview window

(In reply to Germano Massullo from comment #1) > I have noticed that the same problem happens also with > obs-studio-26.0.2-2.fc33.x86_64 I'd suggest reporting a separate issue for this as I can confirm the transparency issue with OBS Studio on KDE Neon User Edition but not the Gwenview one.
Moving to gwenview until something suggests kwin is at fault. > I can confirm the transparency issue with OBS Studio FWIW, I fixed that in OBS. It was caused by the client creating a window from a widget. This is almost certainly the case here: [1295222,105] -> wl_subcompositor@15.get_subsurface(new id wl_subsurface@50, wl_surface@47, wl_surface@36) it's randomly creating a new subsurface, which means it's creating a sub QWindow.
Aha, the subsurface is actually deliberate This bug appears when using "animations" == "opengl" in the settings.

Ok so I can avoid filling a bugreport in OBS Studio right?
