Hi Ulli, I am using Windows 10 and 3.4. Tone curve module works fine for me. Make sure it is activated and try clicking within the module because sometimes I only get the histogram revealed once I have clicked on the line. I cannot replicate the total blank view you have here.

Just installed 3.4 on Windows 10, funnily the tone curve is not visible, i see an empty grey space. I can click and drag there, and the image changes, but the curve stays invisible (included a screen shot). I checked the rgb curve, that one looks completely all right.
