telegram-desktop doesn't work after update to 2.8.11-1


It starts, there are two processes, but no window anywhere:

6457 ? Sl 0:00 \_ /usr/bin/telegram-desktop -basegtkintegration :1.212 org.telegram.desktop.BaseGtkIntegration-870a3dfc19d4f5513cd82393a94839c0
6459 ? Sl 0:00 \_ /usr/bin/telegram-desktop -gtkintegration :1.212 org.telegram.desktop.GtkIntegration-870a3dfc19d4f5513cd82393a94839c0


Here are the error messages:

I've found that it doesn't work with QT_QPA_PLATFORMTHEME=gtk2

The previous version of Telegram showed warnings about this variable and ignored it.
New version doesn't warn anymore but fails to show the window.

It shall be unset explicitely for the Telegram app somehow.

(edit: spelling)

And the variable QT_STYLE_OVERRIDE shall be unset too.

New versions splitted gtk usage to separate processes, so it's supposed to work. This is some bug.

The issue seems to persist with 2.8.11-2 from earlier today.

these three patches should fix that (and gtk + webkit2gtk can go to optdepends)

Should be fixed now. Please confirm.

It works now.

Thank you!
