For some time now - probably back to Vegas Studio 16, certainly in VP17 and now in VP18, I have been unable to use the Intel 520 GPU. The initial VP18 release would crash when using the new AI Style Transfer (thumbnail views) with Intel enabled, but release 334 seems to have fixed that. But the video preview window is just blank! If I select a photo or video that has a different frame size with auto preview, it see it for one frame - then blank. After 5 seconds another flicker as the main video is visible for one frame then blank. I know it's just a little laptop, but it would be nice to zing up the rendering with a bit of GPU!
The Trimmer window is fine. Indeed, when the trimmer window is open, the preview windows displays the current frame. Back to blank if I play the video preview.
Ho well, back to no GPU - when at least it seems really quite stable now - which is nice.
Please tell me if there are specific details about this laptop or VP configuration that might help.
