Sorry to hear you are having trouble.
many games and programs/apps should never be compatible with CursorFX for very obvious reasons i.e. they have their own cursors in addition to another engine for rendering than Windows standard GUI
Very true and any workaround would have us doing hacky stuff with DirectX as well as triggering every anti-cheat measure any game might have.
The OP should not have been lead to believe that we would work around such things - our mistake long ago.
it messes up the cursor making it disappear while in the menu, appears again as soon as i move the cursor out of that right-click menu,
If you do not have CursorFX installed in the default location:
C:\Program Files (x86)\Stardock\CursorFX
Odd things can happen if CursorFX works at all. If you do not, uninstall, reboot, reinstall in the default location and see if you still see your issues.
CursorFx Cursor but as well as in the right click menu of steam in the windows taskbar,
Again, if you have it installed in the proper/default location, please send a link to a video of exactly what is happening. You can record the video with any number of free capture tools, including natively with Windows 10 (WinKey + G) and upload it to a cloud file sharing service (GoogleDrive, OneDrive, DropBox, etc).
