Problem about Save screenshot

I met a problem when using file --> save screenshot.
Everything looks perfect when I about to save my image:

But actually it comes out like this, the middle part somehow being erased

I had tired all the format(jpeg, tiff, bmp, png), they all look like this, any help?

This is indeed a bug in previous versions of ParaView when saving screenshots at a size larger than the current widget. It has been fixed for ParaView 5.7.

Thanks for the information.

By the way, 5.7 should be out in the early June timeframe.
