3. Photoshop/Camera Raw version number Photoshop V22.1.1
4. A brief description of the problem.
Setting: Macbook Pro Connected to Razor Core Egpu with Radeon RX 580.
I have selected "prefer external egpu" in app. Phootshop recognizes my egpu. When i open an image, it displays blank on the canvas. However I still can see the image in the layers section. Image also appears in camera raw and other panels like liquify. I have tried to reset preferences, tried all different modes in drawing mode and no use.
For now I have a workaround. I first disable graphics processor and then open the image. Once the image displays, I enable my graphics processor again and continue working. but I have to do this for every pic i work on. Plus it is slow when zooming in and out of pic. I can confirm the Egpu is working this way as i can see the gpu chart from activity monitor.
Note: I dont have these issues when connected to an external monitor. Seems like photoshop has this issue when I directly use egpu with MacBook Pro internal monitor without an external monitor.
Thanks, yeah, still trying to nail things down; we are modernizing many of the GPU calls and it's possible that things will 'just work' once we get to retiring the offending code. There were some issues with Big Sur (11.0/1) and external monitors, but I'm not sure that is this issue here, and will keep working on it. Still needs to work in the single monitor case.
