XnView Software

XnView: MP 1.4.0 - 64 bit
OS: Ubuntu Linux 22.04 LTS - 64bit, XFCE 4.18 (packages from xubuntu-dev ppa, ppa:xubuntu-dev/staging), Greybird gtk theme

After opening XnView there's a wrong background/color on some ui elements of program. E.g. unreadable tooltips, wrong background in places, etc.

Effect: Some ui elements appears incorrect after program has been launched. Quickly changing theme and returning to previous solves the problem until restart of application. Screenshots:



To reproduce:
1. (optionally) set another user, log in to it
2. Start XnView while using XFCE 4.18 environment, making sure QT_QPA_PLATFORMTHEME env. variable is set to gtk2 (xubuntu has it on /etc/X11/Xsession.d/56xubuntu-session), complete initial setup if prompted, make sure theme selected during setup is default
3. Observe incorrect appearance of the program, notice appearance returns to normal after changing theme and returning to the previous one.

Actual behaviour (bug): Incorrect gtk theme appearance

Expected behaviour: Gtk theme appearing correctly, no wrong backgrounds and/or colors in places.

no such problem with previous version?

Haven't noticed a problem in previous version, only recent version broke. Could reproduce on a clean user profile where the default Xubuntu theme is Greybird, display server is Xorg.

with 1.3.1 no problem?

1.3.1 works fine, after downgrading tested in a clean user profile with no xnview config files present, can confirm 1.4.0 and newer are broken.

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.4.2. Please check and confirm the bug fix here.

Home page still says 1.4.1, though linked deb is 1.4.2. Tested, no theming issues so far, theme appears ok upon load, tooltips readable.

Still happens on 1.4.2 on Arch Linux (xnviewmp-system-libs 1.4.2-1).
