Libhandy: HdyLeaflet window misbehaves in some situations

[moma]

Re-hello all,

Look, I can see a small malfuction (bug) both in the handy-demo and in my own test application.

The HdyLeaflet window misbehaves if the window has a certain size (or edging close to that size).
Please take a look this screencapture clip: “Screencast 2019-04-12 21:25:05.mp4” on

When the window goes berserk, there is no way to make it sane again. Its internal state stays in imbalance. Sometimes it starts to fire the notify_fold_cb() callback constantly.
One has to exit the app.

This is a small issue, but may cause trouble.
Version of my libhandy is 0.0.9-1.

$ apt-cache show libhandy-0.0-dev

Re-hello,

Would someone take a look at my (test) application.
Why does the headerbar start flashing in some cases?

The code:
Radio-011.tar.xz

$ cd Radio
$ meson . _build --reconfigure
$ ninja -C _build
’
Run:
$ _build/src/gnome-radio
