Toolbar icon for matplotlib not showing

The matplotlib toolbar icon doesn't show up with figure windows as highlighted in the red circles.
I am on the Qt5Agg backend and when I switch to TkAgg, the tk icon shows up.
The reason I am curious was that it was working fine until a few days ago but updating some packages broke it.
On Anaconda 5.2.0, matplotlib 2.2.3 and the image is attached.

How to enable scrolling with a touchpad (IntelliJ)?

My touchpad works fine with all other programms btw.

Cannot set application icon for a GTK# application in Monodevelop 3.1.1

I set the icon as described in https://stackoverflow.com/a/12491626/67824 but it still shows as a generic app icon (grey screen with green "exec" text) in the dock and in the ⌘+tab application switcher (both when I run it from MonoDevelop and when I run it using mono foo.exe). I know it can be done, because when I run a mono-compliant version of LINQPad I'm seeing the LINQPad application icon.
I also use the SetIconFromFile method in the main window's class. Example below where my icon is copied to an Images folder at the root of my application:
this.SetIconFromFile(string.Format("{0}{1}Images{2}Logo.ico",
System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().Location),
System.IO.Path.DirectorySeparatorChar,
System.IO.Path.DirectorySeparatorChar));

wxTaskBarIcon sample

I have successfully built wxWidgets, 2.9.4 and the samples on Mac OS X, xubuntu and WinXP. Running the taskbar sample on all three platforms, there is an icon on the task bar but also an icon showing a running application. This is not normal task bar app behavior, right?
It is normal taskbar behavior. wxTaskBarIcon adds the icon to the system tray. on Windows the application's icon in taskbar is controlled by other API.
See this and this.
