Qt6 (with Flatpak): FontDialog doesn't work


I got a report that in CudaText (Flatpak version with Qt6) FontDialog doesn't paint itself. Resizing/closing of dialog works.

Post in the linked issue:

Interesting, if I run the flatpak's executable directly (bypassing the flatpak container), this issue does not occur:

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/.local/share/flatpak/app/io.github.cudatext.CudaText-Qt/current/active/files/lib $HOME/.local/share/flatpak/app/io.github.cudatext.CudaText-Qt/current/active/files/bin/cudatext

I have Qt6.7 in my host OS, while the flatpak currently uses 6.6. Unfortunately, we have to wait until the next stable release of Lazarus before it'll compile Qt6pas with Qt6.7.

Lazarus does not have anything with TFontDialog, it's pure Qt dialog - QFontDialog.
