Strange things happen when I use Colour Balance and Curves

I didn't know how reliant I am on colour balance and curves until now. Please help

When I use curves to strengthen or lighten my line work something weird is happening. It is making other parts of my image disappear. Even if it's not on the same layer, suddenly a bit of another layer will be missing a chunk at random.

And sometimes if I select an area of colour to change using Command + B, i.e. colour balance, it will turn that whole area multi coloured and patterned as soon as I find the colour I want and hit enter or even if I manually hit 'OK'. It's as if I applied a filter,  which I haven't.

Please, does anyone know what the problem is?

It's super frustrating and I can't find the right wording to explain and find an answer to it.

I think same think might be happening when I do Command + U.

Grrr.

Thanks!

    Hi

    You don't say what version of Photoshop you are using or on what operating system (I gather it is a Mac from your use of the Cmd button). It would be helpful to do so.

    The symptoms you describe sound GPU related so I would look in Preferences at the GPU settings and try changing the drawing mode to Basic then restart Photoshop.

    As an aside it it often better to use adjustment layers and masks rather than the menu versions of Curves and Color Balance as adjustment layers allow you to readjust the controls and the masks later.

    p.p.s. I think that GPU thing has fixed it btw, thank you!

    How did you know and what is the difference between basic and advanced GPU? Will it affect anything else?

    Hi

    The drawing mode settings set how much of the screen drawing work is put onto the GPU card and how much on the CPU. You may see a difference in screen drawing speed but given that some functions are still using the GPU then the real world difference may be minor.

    You can always try the higher settings again after an Operating system update where the GPU driver may also be updated
