Crash on startup with "QPaintDevice: Cannot destroy paint device that is being painted" #227
Comments

I'm having the exact same issue (using Fedora Silverblue 38). The AppImage version launches fine. I've reported a bug upstream with backtrace info: https://bugs.kde.org/show_bug.cgi?id=470045 |
|
I'm not a developer, just a user, but can also confirm this issue on my Fedora 38 Workstation installation (not Silverblue) I can't pin it down which was the last working version, though. My output while running it slightly differs:
General infos:
Just in case: |
|
I can not reproduce on a fairly up-to-date Fedora Kinoite so not sure where the issue is. |
|
If that can be useful: CPU: Intel Core i7-2600K × 8 |
|
This popped up on Twitter too. Is there more info needed, or something I should check to see whether it could be a cause, or anything else I could do? I'm reluctant to reinstall my whole OS to see if a fresh installation would fix it, and reinstalling the flatpak itself didn't fix the issue. |
|
It looks like this breaks on non KDE Desktops as you're on GNOME and above it's Silverblue. Not sure why however. |
|
I have had this issue with kdenlive directly from my package manager, and was solved by installing "qt5-graphicaleffects" on my system, though I think the package is named "qt5-qtgraphicaleffects" on Fedora. I have had the same behavior as @travier here with it working fine on KDE but not elsewhere, perhaps this package is being installed as a dependency of something else on KDE. |
Unfortunately, I already have that package installed. Maybe it needs to be a part of the Flatpak runtime, or something like that? |
Same here: |
|
Just in case, i have changed the laptop (now on AMD Renoir 4800H) and with other Gnome Shell Themes. I remember that some programs wouldn't load due to the NVIDIA driver - Switching to Intel or AMD via PRIME did the trick. Is there a way for us to compare our systeminfos? Does anyone here got it work under Gnome (be it Wayland or X11) on F38 Workstation Edition? Edit: The kdenlive version from the Fedora repo starts just fine, but there is the same error message... Maybe that is just a feint / false friend ?

@tcitworld My own logs look very similar, except they end abruptly when the crash occurs: My |
|
Possible Upstream Report: https://bugs.kde.org/show_bug.cgi?id=443574 Might crash for everyone with working hardware accelerated playback (and enabled setting) |
|
I tested that now by removing the Kdenlive flatpak, and then the whole ~/.var/app/org.kde.kdenlive directory. Then I reinstalled the Kdenlive flatpak, and it started up just fine. After enabling that GPU processing option in the playback settings, Kdenlive started crashing again. I don't remember enabling that before, but at least now I can get Kdenlive working again. So, in summary, the bug seems to be upstream after all. I'll close this report because there's already an upstream report. |
On a fully up-to-date Fedora Workstation 38, the latest Kdenlive flatpak crashes on start. Trying to start it again, it asks me if I want to reset my configuration file, but even answering "yes" doesn't solve the issue. I didn't see anything about QPaintDevice in #161, so I made a new issue for this.
Running from the command line produces this output:
