Photoshop CS was commercially released in October 2003 as the eighth major version of Photoshop. Photoshop CS increased user control with a reworked file browser augmenting search versatility, sorting and sharing capabilities and the Histogram Palette which monitors changes in the image as they are made to the document. Match Color was also introduced in CS, which reads color data to achieve a uniform expression throughout a series of pictures.
After some local OS and winecfg adaptations, PS works as expected.
All brushes, effects, and rendering (e.g. liquify, lightning effects) functions work.
TLDR; after specific adaptations, PS works as advertised.
What does not
 On Xubuntu/ xfce, ALT key in PS doesn't work.
 With the install of wine + PS on a box with Xubuntu 20.04 LTS, upon boot, the "wine window with PS" becomes unresponsive. This is accompanied with extreme CPU loads. Menus do not respond, and it is not possible to minimise the wine window+PS (i.e. Always on Top). In some occasions, after long periods (e.g. 30 mins), after repeated clicking on the PS menu, the windows open and function is restored. In some cases these symptoms are accompanied by PS components "flickering" (think low refresh rate kind of).
 ALT key in PS doesn't work.
Solution: On Xubuntu, disable SYSTEM > WINDOW MANAGER TWEAKS > ACCESSIBILITY > "Key used to grab and move windows"; set to "None". Explanation: By default, this is set to the ALT key. This disables the ALT functions in PS (e.g. select target for Clone Stamp).
 The "wine window with PS" becomes unresponsive, PS components "flicker".
Solution: In winecfg > Graphics > disable/ untick "Allow window manager to control the windows". This will launch PS in its "native" window, and speed and response is restored. This approach works both on Intel and AMD GPU boxen. "Window decoration" can be left ticked.

Thanks to earther for the following email:
I was having problems with the Photoshop 7 ALT-Click keybinding in a new Debian install running Compiz. I did the standard window manager tweak but it still didn't work properly. Then I discovered an ALT-Click keybinding in the Compiz Window Management > Move Window > Initiate Window Move settings. I changed it to 'super' like in Gnome window management and voila, it seemed to get it working again in Photoshop. You might want to add that bit of info to the clone tool info on the Photoshop 7 page. earther
