Summary0016802: Issues with "gtk2" application setting
DescriptionOn ubuntu 22.04 dark theme with <empty> or "gtk2" scribus <theme or appearence> ("Apparence" in french UI) choice (but not "windows" or "fusion") :

- the "tick" next to "Insert (menu) / Sticky tools" option doesnt appear (maybe it's black tick on black), whether "1.5.1" or "1.5.1 dark" icons are choosen. (but it looks like clicking this options makes it work)

- all checkboxes have disappeared (same as HTML's "display: none"). Eg : Application's settings / Display / Page , or Album, or Hyphens usw ; or right-click-on-frame "lock frame" submenu options.

- dialog's input boxes have no border at all. When their content is empty, there is absolutely no hint that there is an input zone.

TagsNo tags attached.

Unable to reproduce in my Ubuntu 22.04 VM.

Gtk2 platform theme is a legacy Qt theme which is not maintained anymore. Last commit in qtstyleplugins repo now dates from more than 5 years:

Last time I checked, the code would not compile with Qt 5.15. So... If you are using gtk2 theme, you are clearly looking for problems.

When so bad and not maintened, then maybe the "gtk2" option shouldnt be proposed anymore ?

It should not be the default setting (It looks like the default = <empty> setting is in fact "gtk2")

The gtk2 theme is not installed by default on Ubuntu 22.04 in the first place. I had to install the qt5-style-plugins package manually to get it.

We cannot to anything in this case. The default setting is decided by your system.

? i didnt install it neither. Would appimage be responsible for packaging it ?

Ah! You're using the appimage! It seems that the linuxdeployqt tool used to generate the AppImage indeed automatically bundle it whenever possible:

A few days ago, the bundling of all gtk related plugins was removed from the alternate linuxdeploy tool and its linux deploy qt plugin:

I asked probono on IRC if he could fix linuxdeployqt to stop automatically bundling this gtk2 plugin. It would still be possible to include it with an --extra-plugin option.

I committed a first patch which removes gtk2 plugin from AppImages generated by CI. It should be ok as long as system images does not have gtk2 plugin pre-installed.
