ReText freezes when attempting font change (both editor and preview)

[lucknaumann]

Hi. As the title says, the program freezes when attempting a font change with both the editor and the preview. The second either font dialog pops up, the program freezes and needs to be terminated, regardless of launching from the terminal or from the standard application launcher. This doesn't happen with the Ubuntu repository version or the python version.

Console output (the first part prior to ^C is the initial launch, the rest is after it froze - probably obvious)

Interesting. I cannot reproduce this, although my environment is GNOME, not KDE.

However from your description it seems like it's related to portals: if you run ReText normally, Qt shows the font dialog directly, but in Flatpak, it goes through the portal.

But I am curious: does this happen with other Qt apps run in Flatpak?

E.g. the random app that I just found is Clementine: if you go to Tools → Preferences → Notifications and select “Show a pretty OSD” option, then the “Choose font…“ button will become active.

[lucknaumann]

I don't have a lot of Qt apps as Flatpaks, so I installed KWrite and it was fine. I know it's a KDE app, but Clementine had old dependencies, so I figured KWrite was good enough.

Can you post the output of vainfo?

I tried this in Debian KDE (virtual machine) and had the same issue. Maybe this is just a Plasma 5 issue?

[lucknaumann]

@Mailaender Duplicate? Stale? Hardly! And I've serious doubts regarding "can't reproduce" as I've reproduced this plenty. But I've no doubt regarding "won't fix" and "not planned".

@mitya57 You might want to pack the Flatpak yourself, if you care about this version at all.

No matter. I've uninstalled all versions of this program anyway.

[Mailaender]

You yourself said this also happens outside of Flatpak so it is not a sandboxing/packaging issue.

[lucknaumann]

No. That's not what I said. I said it only happens with the Flatpak, not with the repo version or the python version. To quote myself --

This doesn't happen with the Ubuntu repository version or the python version.

Sounded like the opposite.
