KB2670838 causes gdi+ memory problems and breaks my application

Hi,

A number of my applications users, including my self suffer direct out of memory errors or System.ArgumentException: Parameter is not valid errors when creating a new Bitmap using System.Drawing.Bitmap..ctor(Int32

width, Int32 height, PixelFormat format).

The errors stop upon de-installing KB2670838. There is a direct link between this patch and the errors.

This is an application that has been running steady for years and now suddenly stops functioning with this Windows Update.

It is an application that uses a large ammount of Bitmaps (5000+) and up to 500MB of memory to store these.

Using visual basic.NET to compile the application.

I think it is related to changes in the Windows Imaging Component that is utilized by GDI+. Anybody any idea why, what or how i can make my application work as it used to without forcing users to de-install KB2670838?

I have never had a Windows Update break any of my software products before, it is quite an awfull experience to be so badly surprised by this :(

best regards,

Vic
