Memory Leak using OxyPlot --> Canvas?

[olfk]

I observe strange behavior when trying to use OxyPlot. There seems to be a memory leak.

• Build https://github.com/AvaloniaUI/oxyplot-avalonia
• Run AvaloniaExamples, select 1st item AlignedAxesDemo
• Resize the window several times
• Watch memory consumption

The example is built against Avalonia 0.6.1. It works fine. Memory usage goes up initially and then stays constant.

Now try to convert it to Avalonia 0.7.0. PixelWidth / PixelHeight has to be replaced by PixelSize struct in order to build. I did this on my fork.

• Build https://github.com/olfk/oxyplot-avalonia (or update nuget packages to 0.7.0 and do small fixes to compile)
• Run AvaloniaExamples, select 1st item AlignedAxesDemo
• Resize the window several times
• Watch memory consumption

With Avalonia 0.7.0 Memory usage increases with every redraw of the window.

I know that might be caused by OxyPlot. But the code is 99% identical (just the Bitmap PixelSize thing that changed), and does not have a memory leak with 0.6.1.

Can this be related to Canvas oder Rendering in general?
