SUMMARY Prior to KDE Plasma 5.27.0 I had no issue with launching flatpak Kalk. I updated last night and now I cannot launch Kalk anymore. The first error is complaining about network (which I don't see why Kalk would need) and then when I granted it network it fails for another reason. This might be due to a conflict with the new Discover KCM flatpak permissions and Flatseal? Putting severity urgent as I rely on kalk daily and have to use my phone currently lol. When launching in Konsole this is printed: without network permission, which I used to not give prior to 5.27.0 Warning: fallback to QtQuick software backend. Qt: Session management error: Could not open network socket QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0 ........... this is printed about 50 times .......... after giving network permission Warning: fallback to QtQuick software backend. QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0 ........... this is printed about 50 times .......... STEPS TO REPRODUCE 1. Update to KDE Plasma 5.27.0 and have flatpak-kcm maybe? 2. Try to launch flatpak Kalk OBSERVED RESULT Application does not launch EXPECTED RESULT Application launches.

I don't seem to get this issue, could you please try updating all your flatpaks? Specifically, the KDE runtime flatpaks.

I did a full flatpak update after a computer restart as usual after doing a sudo pacman -Syu. I did a restart again now and Discover says there's nothing new for flatpak. flatpak list --runtime Name Application ID Version Branch Installation KDE Application Platform org.kde.Platform 5.15-21.08 system KDE Application Platform org.kde.Platform 5.15-22.08 system KDE Application Platform org.kde.Platform 6.3 system KDE Application Platform org.kde.Platform 6.4 system
Could you please try resetting your flatpaks permissions for kalk? In my flatseal, I don't see network being needed to launch...

The only difference between what I had and the default was disabling GPU acceleration. It still prints the same line 50 times. If I reset to default and give it GPU acceleration the only difference is it no longer prints this specific line "Warning: fallback to QtQuick software backend." but still prints the below 50 times. QFont::setPointSizeF: Point size <= 0 (0.000000), must be greater than 0 You have the new flatpak-kcm installed?
sort of my bad. My flatpak kalk was not fully updated. I forgot I downgraded it with the last updated because the new font setting made it unusable where everything is tiny. Regardless I updated to latest version and kalk still does not launch. In fact it does not even print anything besides missing network permission in Konsole if I do flatpak run org.kde.kalk. If I give it network permission it does not even print anything at all so I cannot even give a useful log.
I don't really know what else to try other than running `rm -rf ~/.var/app/org.kde.kalk/cache/` to remove the Qt cache...

It works after deleting cache. I cannot explain what go wrong, last night before I was 5.27.0 all good, then update full system, flatpaks, reboot and no longer work this morning lol.
