[Bug 1149986] New: telegram-desktop cannot be started with enabled GTK integration and libqt5-qtstyleplugins-platformtheme-gtk2 installed

Currently this is resolved by a conflict of telegram-desktop with libqt5-qtstyleplugins-platformtheme-gtk2 which leads to cunfusion of users (bug 1148509) Ideally the root cause should be found and patched. A package without the conflict for testing can be found at https://build.opensuse.org/project/show/home:tux93:tdesktop-no-conflict -- You are receiving this mail because: You are on the CC list for the bug.

Due to libqt5-qtstyleplugins-platformtheme-gtk2 being hard required by Cinnamon GTK integration will be disabled again on the main package, a branch with it enabled will be kept for further testing at https://build.opensuse.org/project/show/home:tux93:tdesktop
Request for review: I used the gtk2 patch along with some other patches from Arch PKGBUILD and disable the GTK integration, and removes the conflict. The package works on my KDE desktop. Could you please test it on GNOME and/or Cinnamon? If it works on both platforms, I will submit a request to server:messaging. My latest packaging is at: https://build.opensuse.org/project/show/home:nuklly:branches:server:messagin....

The patches remove the built-in Open Sans fonts and uses system built-in Open Sans fonts. So it may pick-up an alternate if some fonts are missing in your system. Check "Font Error" in your log.txt file for more details. Sorry I am still searching for flags to enable debug logs in Telegram. Enabling debug messages will be very helpful to further diagnose the qtstyle plugin conflict. -- You are receiving this mail because: You are on the CC list for the bug.

Could you please create a file called "withdebug" with single line content "1" in ~/.local/share/TelegramDesktop/tdata, then start telegram-desktop? This should be enough to turn on the debug mode. After turning on debug mode, please share the log.txt file when there is a conflict.

Tonight I debugged it on a xfce virtual machine. Some updates: 1. The libqt5-qtstyleplugins-platformtheme-gtk2 package has two so files: platformthemes/libqgtk2.so and plugins/styles/libqgtk2style.so. The problematic one is libqgtk2.so. 2. Qt plugin loader searches the folder /usr/lib64/qt5/plugins/platformthemes and finds two plugins: libqgtk2.so and libqgtk3.so. It incorrectly selects the libqgtk2.so even if it is a gtk3 environment (xfce/gnome in my case). If only gtk2 plugin exists, it has no problem. So it is really a Qt bug. Up to now it is not clear why Qt prefer the gtk2 plugin over the gtk3 one, and whether a workaround exists. -- You are receiving this mail because: You are on the CC list for the bug.

I have already found the root cause. In https://build.opensuse.org/package/view_file/KDE:Qt:5.13/libqt5-qtbase/libqt... , openSUSE is prioritizing gtk2 theme over gtk3. This is incorrect.

Then I believe the problem is why the theme falls back to default instead of using the GTK3 version even though the theme in Qt is set to "GTK3". It shouldn't be GTK2 related anyway. -- You are receiving this mail because: You are on the CC list for the bug.
http://bugzilla.opensuse.org/show_bug.cgi?id=1149986 http://bugzilla.opensuse.org/show_bug.cgi?id=1149986#c21 --- Comment #21 from Xu Zhao <i@xuzhao.net> --- After some research, I have finally fixed this problem completely. This is because when the application starts up (step-1), it uses gtk2 theme prior to the gtk3 theme (specified by qt5-base). However, when later Telegram initializes the gtk environment (step-2), it searches for the gtk3 library first, if found, use the gtk3 library. If not found, use the gtk2 library. When both gtk2 and gtk3 libraries co-exist in the system, the application will first use gtk2 theme to start up (in step-1), then use gtk3 libraries to initialize (in step-2), mix using two libraries causes a failed start. To fix this, I have created a patch to let Telegram always favor gtk2 over gtk3 during initialization, since openSUSE has chosen to enable gtk2 theme by default in qt5-base. Please help test my patch at: https://build.opensuse.org/package/show/home:nuklly:branches:server:messagin... on XFCE, Cinnamon, GNOME, etc. The version works on KDE. Note that I have to add the libappindicator1 as a hard dependency because Telegram can only use gtk2 with libappindicator1 for notification. (In reply to Marcel Kuehlhorn from comment #19)

Good question, maybe one of the maintainers could answer that?
The gtk3 plugin is only a platform plugin, but not a theme or style, so it would use Fusion (or some other theme) with GTK 3 dialogs. The gtk2 style plugin is a complete style, theme and platform plugin.
I see. Sorry I am not familiar with this part of Qt. Could you please provide more details? Why prioritzing gtk3 platform plugin and using other gtk3 theme over gtk2 style plugin(w/ theme and style) is a problem? -- You are receiving this mail because: You are on the CC list for the bug.

Just curious, why does openSUSE still have the gtk2 priortise patch in libqt5-qtbase? It doesn't make any sense to me to still favor gtk2 theme over gtk3 on Qt applications. Removing this patch will solve this problem automatically, based on my understanding of this bug.

Qt does not support GTK3 themes, only GTK2 ones. -- You are receiving this mail because: You are on the CC list for the bug.
