Latest version ( 0.3.7 ) doesn't copy text to clipboard

[pizzadude]

I'm sorry that I keep discovering issues, but I thought I should let you know that the latest version ( 0.3.7 ) doesn't copy text to the clipboard, atleast on Fedora KDE Wayland. The AppImage of 0.3.5 works. In the CLI output it recognizes the text fine.

Another thing is the AppImage has notifications and tray support, but the flatpak doesn't. Also, the flatpak sometimes doesn't copy to clipboard, even on older versions. The AppImage of 0.3.5 is the most reliable (for me).

Edit: I can confirm that the AppImage of 0.3.7 has the same issue. (0.3.5 works though)

You are using Fedora 35, right? (I tested on 36, there it seemed to work).

The fact that both system tray + notification are affected is making perfectly sense, as notifications are actually handled by the QSystemTrayIcon. I already noticed, that the tray icon and notifications seem to behave a bit different in flatpak vs. appimage. The clipboard problem is more surprising to me, though...

Sorry, that the flatpak is a bit of construction site atm, but I kind of anticipated problems in the first versions after introducing it. So I'm very glad that users like you report any issue they find! :-)

All those issues?! Or only the clipboard one? :open_mouth:

Could you please run:

./NormCap-0.3.7-x86_64.AppImage -v debug > normcap.log

and then share the log files content here?

Nope, Fedora 36 KDE, fully updated.

Only the clipboard one for the 0.3.7 AppImage.

Hi @pizzadude,

thanks for the log files. I'm now able to reproduce everything.

For better issue tracking, I created #240 for the notification/tray icon problem, while limiting this issue here to the not working clipboard.

I already started looking into it, but it doesn't seem to be something obvious... My best guess is, that an updated introduced an incompatibility which breaks the copy-to-clipboard functionality of Qt/PySide6, but that's just gut feeling.

[dynobo]

Short update: I confirmed, that QT's clipboard works even more unreliably on the newest Wayland, as it did in the past. It seems like pasting doesn't work at all if no window is visible (and maybe even active?). As I expect these problems to arrive in other distributions, too, I'm working on an integration with wl-clipboard. I'm not super happy about adding a new dependency to NormCap, but I don't see a good alternative. Stay tuned.

[dynobo]

Should be solved with the release v.0.3.8. Please re-open, if it's not.

Hi, it works now! Thanks. :)
