An odd "phenomenon" while usage MetroWindow and Canvas.

[DeputyOfCopyPaster]

Hello everyone!
Metro 1.6.5
I've noticed that something wrong happens with images (Canvas) while Metro framework usage.
I performed two simpliest tests and I had been surprised that pure WPF project is deprived of such a "phenomenon" as follows:

In other words the pure WPF project handles well with all Canvases inserted.
So, my question is, how to get rid of that "phenomenon"?

Please any insights on that issue?

thanks in advance!

An Update: the same disaster has v.2.00-alpha0490.

@DeputyOfCopyPaster can you upload your sample? I have an idea, but I have to try it tomorrow if it works.

Happy coding

@timunie

ok, please look at the sample attached. To see difference look first at pure WPF project, then add MetroWindow by yourself and catch the "phenomenon".

I really hope you make it!

@DeputyOfCopyPaster The SnapsToDevicePixels of the MetroWindow is set to true, so all inner controls inherits this value. You can fix this by changing the SnapsToDevicePixels for the Canvas and set it to false.

<Canvas SnapsToDevicePixels="False">
</Canvas>

An Update:

@timunie, @punker76
your link above (from STACK), led to the assumption that it might make a sense.
As it turned out, I 've gotten better Canvas' behaviour as it was before. At least the lines had stopped disappearing. 👍
<Canvas SnapsToDevicePixels="False"> </Canvas>
