Just installed the update to Photoshop CC 2020 but Lens Blur now fails to work. I get a total checkerboard effect and if I click OK the filter simply fails and leaves the image blank/checker-boarded. HELP !!!
Engineering got back to me. Looks like these Intel(R) UHD cards aren't supported at all and should have been blacklisted. The workaround is to disable Preferences > Performance... "Use Graphics Processor" and retry the filter.
These cards will be disabled and Lens Blur will use CPU instead in future releases. So having a dedicated card is the best solution. Thanks.
