Incorrect title bar color in Windows 8.1 with paint.net 4.0.1

[Rangi]

Since I chose a dark window color in Windows 8.1, I'm using a theme which changes the title bars to white instead of black text. However, paint.net 4.0.1 has a custom title bar (presumably to allow the image thumbnails to overlap it). The text is left-aligned and black, unlike my other windows with centered white titles. On dark backgrounds this is unreadable.

Can you please post a screenshot

Also, the title bars of the floating windows (Tools+History+Layers+Colors) are larger than they used to be, which cuts off the "Tools" title. This does not happen in Windows 7 SP1 x64: http://i.imgur.com/MpDX8sS.png

Seems like a bug in the theme

Okay then. The theme author says they changed these colors from black to white:

 

AeroWizard <AeroWizardStyle>.TitleBar.<default>:TEXTCOLOR:COLOR
AeroWizard <AeroWizardStyle>.TitleBar.Inactive:TEXTCOLOR:COLOR
Window <WindowStyle>.Caption.<default>:TEXTCOLOR:COLOR
DWMWindow.Frames.Window.Top.Active:TEXTCOLOR:COLOR
DWMWindow.Frames.Window.Top.Inactive:TEXTCOLOR:COLOR
TaskbandExtendedUI.Title.<default>:TEXTCOLOR:COLOR

 

How is paint.net fetching the color to use for its title? Maybe I can edit the theme to fix this.

 

Also, the large subwindow titles are still there even with Windows 8.1's default theme: http://i.imgur.com/3PUJR6J.png

The large subwindow titles are just a change in the font size that Windows 8 uses. That isn't a bug. It's a little goofy but they just decided to increase the font size for some reason. I'm pretty sure you can edit the font size in your theme in somewhere in one of the Windows control panels (I know which one it is but I can't remember where it is or how to get to it in Windows 8).

 

For drawing the title bar in this case, Paint.NET uses a Win32 API called DrawThemeTextEx, http://msdn.microsoft.com/en-us/library/windows/desktop/bb773317(v=vs.85).aspx

 

I'm specifying 0 for both iPartId and iStateId, but from some quick research I think I may need to pass in WS_CAPTION and CS_ACTIVE, respectively (or CS_INACTIVE if the window isn't active, I suppose?). I'll file a bug and check it out.
