CPU-Z screenshots looks funny

[milutzu_k]

In CPU-Z F5 key can take a screenshot of the current image and a bitmap (bmp) is saved in cpu-z folder. This screenshot is not rendered correctly in XnView, only the window elements (icon, control buttons, border) are visible, anything else looks transparent. I believe this is a bug in cpu-z but other viewers and image editors (IrfanView, Windows Viewer, MSPaint) manage to render the image correctly. This behaviour is present in all recent versions of XnView (at least 2 years back), in Windows XP SP3, Vista and 7.

Perhaps the alpha channel is bad, do you have tried to disable view>Use alpha channel?
