This information applies to version(s): 1, 2 (Windows only)
Please verify that you have installed the latest drivers for your graphic card by checking the manufacturer's website, as black images usually only appear when the graphic card driver is out of date or incompatible.
Depending on the capability of your graphic card, you might also observe this effect when other programs are using GPU acceleration at the same time. For example, if you work with Adobe Lightroom and DxO PureRAW at the same time, then DxO PureRAW may be adversely affected.
As a workaround, please either deactivate the GPU acceleration for one of the programs in question or do not use them both simultaneously.
