Public bug reported:
In Noble a GtkGlArea widget with transparency doesn't show the GTK
widgets beneath it correctly. This was a regression fixed in
https://gitlab.gnome.org/GNOME/gtk/-/commit/6754765a5a849ecbdd5c5fa60b5a6f80a968133e
(released in 3.24.42).
Test Case:
Run gdkgears:
$ apt source gtk+3.0
$ cd src/gtk+3.0-3.24.41
$ meson _build
$ ninja -C _build
$ ./_build/tests/gdkgears
Click "Alpha" checkbox.
Expected results:
Gears are shown with Gtk window background behind them.
Observed results:
Uninitialized buffer is shown behind gears (commonly looks like repeated
contents of old window frames).
