Title is missing on a WPF's tool window when DPI setting 125-150%

Question

When WindowStyle="ToolWindow" and ResizeMode="NoResize" and system DPI is 125-150% the text on the titlebar disappears. I'm running Windows 7 and WPF 3.5 Any idea why is this happening?

Answer 1

I noticed this yesterday. The ToolWindow part and the DPI are fine, but adding the NoResize causes this.
