Screenshot rendering bugs?

Hello, it seems that I'm having problems with screenshots. Sometimes the screen doesn't fully render and things will disappear, whether it be UI or model

Example :

(The heck has happened to my minimap and my UI?)

These strangely only happen in my WotLK client. My MoP client seem to render the screenshots flawlessly. Any idea why/how to fix?

Have you tried on another computer with the same client? It might be your GPU, maybe drivers, try updating them to the latest version.

I haven't, I'm using my laptop with AMD Radeon HD graphics. It could be the AMD part, I'm not entirely sure. Just wondering why I'm only running into this problem with the WotLK client.

I'll try checking it with my Intel HD Graphic one, see if it will produce same results

Thank you for the advice

Seems to have fixed it. All I need to do is turn on Reduce Input Lag

Now my shots renders well, so far
