You can try and full screen the window with F11 or Ctrl + F, I don’t remember the hotkey for windows.
does not work
One suggestion: In the display setting of Windows, there is a choice of changing the size of text, apps and other items. Try putting it to 100% and then open RT. This might work.
You might also try Alt + Space, then x.
Great!!! Now work!! Thanks Shreedhar!!!
You are welcome
And update to RawTherapee 5.3.
I think the screenshot shows Win Vista… XP did not have that theme.
@heckflosse ah… RawTherapee support for 32-bit Windows systems was ended with 5.0-rc1.
