Plugin layout distortion in Smart client 2018 R2 vs 2017 R2

When I run a work-space plugin in Smart Client 2018 R2, I see a distortion in panels layout, which I don’t see when I run exactly the same plugin in Smart Client 2017 R2

Basically, I have a C# GroupBox container in the center with Anchors, set to “Top, Bottom, Left, Right”. It is supposed to butt up against another GroupBox container on the right( Anchors: Top, Bottom, Right). Dock is “None” for both of them.

However, in 2018 edition, the center container overlaps the right container, either above or below, depending on the z order. And it happens right away, even if I don’t resize or blow full screen the whole application window.

This happens in 2018 edition,

When running the same plugin in 2017 edition, they line up against each other as expected

2017 edition runs on Windows 8

2018 edition runs on Windows 10, if it matters…

I assume the observation is on your side panel. There is a known issue that distortions can happen. The cause is issues with winforms rendered on WPF. There is no fix. The workaround is to redevelop your side panel using WPF. If you start a new plugin project using the MIPPlugin template you will get a skeleton WPF side panel.
