Created attachment 125030 [details] A screenshot of the error SUMMARY When launching Gwenview to open an image, any image, whether from dolphin or from the terminal, it lags for about 30-50 seconds before displaying any image, or even user interface of any kind. A screenshot is attached. STEPS TO REPRODUCE 1. Open any image in any way 2. Bug occurs OBSERVED RESULT Gwenview 'takes a screenshot' of the desktop in the size of it's window, and when I move around, that afterimage persists. It then takes around 30 seconds to load an image, and around 1/8 of the time, it crashes before loading the image. EXPECTED RESULT Gwenview loads the image instantly SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro 18, kernel 5.4 (available in About System) KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.15.0
This also happens when launching Gwenview W/O images. It doesn't occur in other QT apps.
I have this problem too. It goes away when uninstalling kio-fuse.

During the time gwenview is frozen, please run strace -p $(pidof gwenview) and post the output. > Qt Version: 5.15.0 Really? (In reply to ariasuni from comment #2) > I have this problem too. It goes away when uninstalling kio-fuse. That sounds odd, gwenview doesn't use kio-fuse.

closing as per comment 5
I am facing this exact bug on plasma 5.18.4 and gwenview 19.12.3
Created attachment 130869 [details] strace showing recent files issue Anything under '/home/victor/Export' is an NFS mount that is not currently available.
I have had the same issue on my laptop (Desktop works ok) for quite a while. I'm running Arch with KDE on both computers. I had tried re-installing Gwenview, removing the config file and even disabling KDE connect (found a post where someone had issues online). Nothing worked. After running 'strace' it showed that it was trying to load data from '${HOME}/.local/share/gwenview/recentfolders', which pointed to an NFS mount that is not currently active. I deleted the folder and now Gwenview works as expected. I would assume this to be a bug. Not being able to open recent files should not halt the main thread.
