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

When WindowStyle="ToolWindow" and 开发者_开发百科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?

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

I had this problem as well with the following:

<Window SizeToContent="WidthAndHeight" ResizeMode="NoResize" WindowStyle="ToolWindow" Title=Blah">

Switching to WindowStyle="SingleBorderWindow" fixed the issue of the Title text not appearing. So if you aren't set on using a ToolWindow, this works too.
