I've noticed I can no longer switch my input methods while Telegram is focused. This used to work prior the update, in 2.4.11. If I want to switch, I need to focus some other application, switch there, and focus Telegram again. The IBus popup window appears and it seems as if I can actually switch the method but in the end it remains stuck on the old one. I tested this with a random different Qt5 app, Featherpad, to rule out problems with my IBus/Qt5 setup. It works fine in Featherpad. It also works fine in all other GTK and X apps I use. My QT_IM_MODULE environmental variable is set to "ibus", just like prior the update. net-im/telegram-desktop-2.7.1-r1 app-i18n/ibus-1.5.23 Reproducible: Always Steps to Reproduce: 1. Use IBus with more than one input method. 2. Attempt to switch the method while using Telegram. Actual Results: The IBus popup window gives the impression that you're switching your input method, yet Telegram still uses the old one until you switch the method with some other app focused. Then it suddenly recognizes the new method. Expected Results: The input method gets switched like in any other app, including other Qt5 apps, or like in 2.4.11. ; emerge --info Portage 3.0.18 (python 3.8.8-final-0, default/linux/amd64/17.1,

Additionally, using more complicated input methods (such as ibus-hangul) doesn't appear to work at all -- it just outputs latin characters instead of entering the combining mode. Again, this works elsewhere, including Featherpad.
As reproducing this requires setting up some programs I'm not familiar with, could you first test it with the official tdesktop binaries downloaded from https://desktop.telegram.org/ ? Also, for future reference, it'd be helpful to know what your telegram-desktop USE and C(XX)FLAGS flags are, your QT_QPA_PLATFORMTHEME and DESKTOP_APP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY variables.

Okay, this happens with 2.7.1 from upstream, too. So either it's an upstream bug or Telegram suddenly requires something else to be configured :| I think I'll try building IBus with the "kde" USE flag to see if that helps... > Also, for future reference, it'd be helpful to know what your > telegram-desktop USE and C(XX)FLAGS flags are, your QT_QPA_PLATFORMTHEME and > DESKTOP_APP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY variables. Okay, for the record here: USE="X dbus gtk hunspell pulseaudio spell -enchant (-libressl) -wayland" C[XX]FLAGS are the same as the global ones shown in the initial report. QT_QPA_PLATFORMTHEME is unset. DESKTOP_APP_I_KNOW_ABOUT_GTK_INCOMPATIBILITY is unset.
(In reply to Petr Šabata from comment #3) > I think I'll try building IBus with the "kde" USE flag to see if that > helps... That actually fixed it. Hopefully this report will help someone in the future. Closing.
I wonder if there's a way to warn people about this; I can't make telegram-desktop depend on ibus so can't enforce this USE flag...
(In reply to Esteve Varela Colominas from comment #5) > I wonder if there's a way to warn people about this; I can't make > telegram-desktop depend on ibus so can't enforce this USE flag... If want to have a elog/warn message to warn without bothering non-ibus users, you could have a "has_version app-i18n/ibus && ! has_version app-i18n/ibus[kde]" in postinst. Not that it's perfect given ibus might not even be installed yet or those having it might not actually be using it. If there's a lot of other small things to convey, making a wiki page could also be an option, good odds people will find it when having issues.
(In reply to Ionen Wolkens from comment #6) very good suggestions for pkg_postinst/wiki.. also you may take a look at readme.gentoo-r1.eclass if you find the warning/info are tedious..
Well, after a reboot the broken behavior is back even with IBus being built with the "kde" USE flag. Mysterious. I'll let you know if I ever figure it out.
