SUMMARY Running an ffmpeg encode with Shutter encoder, Shutter encoder & ffmpeg crash when I power off the screen (after locking the screen). STEPS TO REPRODUCE 1. Login to the wayland session 2. Start an ffmpeg encode with Shutter encoder (https://aur.archlinux.org/packages/shutter-encoder) & minimize shutter encoder. 3. Startkey+L to lock the screen 4. Power off the screen 5. After a few seconds I head the fans spin down (-> this means the encode has crashed) 6. Power on the screen 7. Unlock the screen (with password) 8. The shutter encoder & ffmpeg processes have disappeared. OBSERVED RESULT ffmpeg & shutter encoder gui have crashed EXPECTED RESULT Shutter encoder should continue working after logging out & powering off the screen. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Plasma 5.27.80 , archlinux kernel 6.6.1 (available in About System) KDE Plasma Version: 5.27.80 KDE Frameworks Version: 5.245.0 Qt Version: 6.6.0 ADDITIONAL INFORMATION: With the X11 session it works.
This is a bug in shutter encoder GUI or the toolkit used there. Please report there.
(In reply to David Edmundson from comment #1) > This is a bug in shutter encoder GUI or the toolkit used there. Please > report there. Just did some more testing: it also crashes with X11 (kde alpha) after the screen auto-locks & the screen powers off (but not always). With stable KDE it WORKS FINE. Doesn't crash (Have tested many times for days). -> please confirm if you are still sure that this is downstream.
BTW Shutter encoder uses java. So this would be a bug in java?
Did some more testing: When logging back in (from the lock screen) after a few hours (X11), the desktop is frozen (icons, kde bar, etc... are unresponsive) but I can move the mouse. And the ffmpeg and shutter encoder processes have disappeared (they have crashed in the middle of an encoding job). THIS PROBLEM DOESN'T EXIST with the stable plasma (I have been running ffmpeg/shutter encoder jobs for days without any issues).
Can you attach a backtrace of what's crashing?
(In reply to Nate Graham from comment #5) > Can you attach a backtrace of what's crashing? Sorry, I have downgraded to stable plasma5 and for 3 DAYS straight have been running up to 7 shutter-encoder jobs in parallel 24h/24 non-stop (and even tested playing heavy proton games at the same time to test the stability) -> it is ROCK STABLE on plasma5 (X11). My encodings are for work & aren't finished, so I can't go back to the plasma-alpha right now. But to make it fast for you so you can trace this very quickly: 1. Download this: https://www.shutterencoder.com/Shutter%20Encoder%2017.6%20Linux%2064bits.AppImage (or the .deb). 2. Load a video to encode in wayland (I encode to AV1). 3. Startkey+L to lock the screen 4. Power off the screen 5. After a few seconds I head the fans spin down (-> this means the encode has crashed) 6. Power on the screen 7. Unlock the screen (with password) 8. The shutter encoder & ffmpeg processes have disappeared. (I am on full AMD zen4 + AMD rx6000 series). -> please tell me if you can reproduce the problem. I am currently blocked with my encoding work, but if you cannot reproduce this (I am sure you will be able to), we will see how I can help you further. Thanks!
