Just to give one more voice for a Linux version.
I dropped Adobe when they went rental, and was one early adopter of Photo and Designer, they were not perfected and I missed some of the functions I used. I work as Technical Director on my own company, and before work as a Tech Artist on a Archviz company. Since I started my business I try to be as open as possible to allow dropping Windows all together, we use Houdini, Blender (before was 3dsMax and Maya), Fusion and Resolve, and Unreal and Unity3D. Right now the only missing key is either supporting proper wine for Photo/Designer, since I ran them on a VM with some other software that is required from time to time.
