Additional Notes
Is this project still being updated? It's absolutely great what you've done here, I'm just wondering. Thanks so much!

Hey @OwenD30,

Thank you so much for your issue report and the screenshots!

To answer your last question first: Yes, the project is still actively maintained and developed. However I have many offline duties including a full time job, so sometimes the development slows down a little bit. In addition, I am considering rewriting the application in Tauri (Rust + Angular), but so far this is just an idea and the current project as it is will be continued. Any contributions, ideas etc. are more than welcome 🤗

Concerning your issue: Have you tried other Qt6 applications under Flatpak, and do they have a similar issue? Under my Linux setup (Arch), I don't face the issue. Which desktop environment are you using, and are you using Wayland or X?

Thank you again and God bless!

Edit: So the problem only occurs in presentation mode? Any other mode and window is fine?

[owendor]

It's only in presentation mode! The rest of the program works perfectly.

I'm on Fedora 40 w/ Gnome 46 & Wayland.

I'm a computer engineering student with limited time on my hands, but I might clone the repo and check it out!

Hello, thanks for your reply!

Then I probably now what the reason for that is: It is the use of the TBGRABitmap font rendering. This has caused some other bugs as well and I am going to provide a bug fix in the next version which should also fix your problem.

I will leave the issue open till I have implemented it.

Dear @OwenD30 ,

I would like to come back to your issue: Unfortunately I wasn't quite able to reproduce it on my Linux setup (Arch Linux). Could you try to install Cantara outside of a Flatpak (or just run the binary) and tell me if the problem still persists?

Thank you very much!
