scribus aborts with wayland protocol error for HiDPI monitor

[Eugene Savelov]

I was able to reproduce the bug by running scribus, restoring my file and launching menu Edit/Javascripts

under wayland-debug it shows below error:

13.2161 A: → [e-mail]()
13.2331 A: [e-mail](object_id=wl_surface@52d, code=2, message='Buffer size (366x251) must be an integer multiple of the buffer_scale (2).') ↲
       | The Wayland connection experienced a fatal error: Ошибка протокола

Happens only on external monitor configured at 125% font scale / fractional scaling and only in qt wayland mode (T_QPA_PLATFORM=wayland)

running scribus in x11 mode resolves this error-
QT_QPA_PLATFORM=xcb scribus

[Eugene Savelov (savelov)]

This bug happens only on external monitor, which currently configured at 125% font scale and fractional scaling. On internal monitor which is configured at 100% this does not happen

[Eugene Savelov (savelov)]

assuming released appimage version 1.6.0 does not support wayland natively and hence does not show this bug

scribus-1.6.0-linux-x86_64.AppImage
Run experimental bundle that bundles everything
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

checked latest version 1.7.0svn compiled against qt 6.4.2 - works correctly
