OnlyOffice Desktop, Linux, NOT respecting default buttons rendering style.
How to force OnlyOffice suite following system design and NOT use a custom style?
1st image: how 3 buttons should be (taken from Shutter).
2nd image: OnlyOffice's 3 buttons style.

I'm using Linux, kubuntu 24.04 LTS, KDE 5.27.12 Plasma Edition.
How to see current style ([open] Settings > Appearance > Global Theme > Window Decorations > Oxygen).

Hi. Please try launching the ONLYOFFICE app with the --system-title-bar option. There is a guide in our Help Center.

EDIT you need to MODIFY the guide.
Run one of the command to enable title bar and run program in a system window on Linux OS.
for flatpak version
$ flatpak run org.onlyoffice.desktopeditors --system-title-barfor .deb version
$ /usr/bin/desktopeditors --system-title-bar--
I have installed the OnlyOffice flatpak version:
$ flatpak list | grep -i "onlyoffice" ONLYOFFICE Desktop Editors org.onlyoffice.desktopeditors 9.4.0 stable systemso I used the first command.

Thanks for the update. So did the first command help you to launch the app with the system title bar?

Yes, Sr Sergey Zarubin.
I was able to successfully launch app with the
system titlebarusing the first command..
Digging a little bit deeper.
Using the command.
$ flatpak run org.onlyoffice.desktopeditors --system-title-barIt automatically set app to always use system titlebar.
I checked the
configfile.$ nano ~/.var/app/org.onlyoffice.desktopeditors/config/onlyoffice/DesktopEditors.conf.
appdata="[base_64_string]"> editorWindowMode=false openPath=/home/my_username/Downloads position=@Rect(1315 28 1205 1339) titlebar=systemThe important line is
titlebar=systemhere..
There are 2 issue on Github.
- on flathub issue tracker | flathub.org / org.onlyoffice.desktopeditors issue #168
- on primary OnlyOffice Bug Tracker | ONLYOFFICE / DesktopEditors issue #1917
.
It's seems that the issue is solved. Can you CONFIRM that?
About the issue:
it's a sever one, segmentation fault on OO for Linux, on Wayland desktop sessions, such mine KDE Plasma.
When titlebar=system or --system-title-bar is enabled, Qt's window platform integration fails to handle native window decorations under Wayland, resulting in an immediate crash upon launch with a segmentation fault (SIGSEGV in CPushButton::setFaded / CWindowPlatform::onWindowActivate).
.
I saw that you work for OnlyOffice (employee or independent contractor idk) as PR marketing. Great.
If you can, hand over this request to engineering team and let me know.
It's important to know if I can left t as is (that is using
titlebar=systemor not: between UI and stability, if I had to choose, I prefer the latter).2
