I'm trying to create Direct2D render target.

This was working fine before but recently it has stopped working and I don't know why & cant seem to figuree out why this has stopped.

I have been on google and trying to figure out exactly why this is happening but cant seem to get any where.

I'm using SharpDx with C# & Directx11

Any suggestions or help would be great.

I've attached some images below:

After several days of trying different things i figured it out.

It seems the issue was being caused by my graphics card driver. Once i rolled back to a previous driver which i know worked everything worked fine as expected.

Note: Using AMG Radeon R9 series card with driver version 21.19.137.1 & Radeon Software version 16.9.2
