The decoration title is cut when selecting another language

[seb128]

Using the current canary daily with rev288, if you select another language on the first screen the win title is cut, for example in french it displays 'Installer Ub...'. That's in a gnome boxes instance but the resolution choice doesn't seem to change the result

This might be somehow connected to the rendering issue. The title is sometimes ok and sometimes cut, when activating and deactivating the window back and forth. The close button has often rendering issues at the same time when the title gets cut.

P.S. The screenshots were taken without libhandy to eliminate it out.

I'll double check after lunch but I think https://bugs.launchpad.net/ubuntu/+source/gtk+3.0/+bug/1960947 solves this too!

Even though this is clearly more like a layout calculation issue, I can't seem to be able to reproduce this after LP#1960947 has landed. It's a bit strange that a miscalculated OpenGL update area would have a side-effect like this, but perhaps it leaves an intermediate layout visible due to a missing redraw.

The title is elided even shorter when running integration tests

A minimal Flutter app + integration test that reproduces the issue: flutter_window_title_issue. I've added a long list of notes there too.

We could replace the GTK header bar with a Flutter widget when I'm done with:
