[Noesis 1.2.3]: Fonts are not released after shutdown

03 Jun 2015, 16:08

Hi,

We recently added a custom font to our game user interface. Now the Visual Studio Debug Memory tracker reports a memory leak. The memory leak only ocures when I use a custom font. Otherwise everything is find no matter how complex my xcml files are. I read that fonts are cached. Do I need to call a separate function to clear the cache when quitting the game? The clear cache seems to be gone in the latest Noesis version.(viewtopic.php?f=3&t=708&p=3923&hilit=clear+cache#p3923).

We are using Ogre and the NoesisUI OgreBinding you provided.

<UserControl
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Height="350" Width="525" TextElement.FontFamily="../fonts/#DIN">
	<Viewbox x:Name="LayoutRoot" RenderTransformOrigin="0.5,0.5">
		<Grid Width="1280" Height="960">
			<TextBlock HorizontalAlignment="Center" Margin="0" TextWrapping="Wrap" Text="TITLE" VerticalAlignment="Center" FontSize="36"/>
		</Grid>
	</Viewbox>
</UserControl>

After quitting the application using Noesis::GUI::Shutdown(); I get a memory leak indicating that the font is still allocated.

{162742} normal block at 0x081CFD60, 32 bytes long.

Thank you!

You don't need to manually clear the cache. It is done automatically.

Before any further investigation, please make sure that all Ptr you own (Ptr<IRenderer> for example) are NULL (by calling Reset()) before calling Shutdown().
