4. A brief description of the problem.

Setting: Macbook Pro Connected to Razor Core Egpu with Radeon RX 580.

Description:

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.
