Problem when running wavelets in two instances of Siril

Hi there,

I believe I have found a bug when doing a wavelet transformation simultaneously in two instances of Siril.
When adjusting the wavelet settings in two instances of Siril, one of the images goes weird or the two images combine as shown in the example.
This happens regardless of image resolution and file type (tested with jpg, png, tiff).

The process goes as follows:

start wavelet on a
start wavelet on b
adjust b
adjust a
→ a goes weird

I hope this is helpful,

This is not really a bug.
Siril uses wavelets by saving a file in temp folder. You cannot use it with 2 different instances.

Thanks for the reply, I was not aware of this. Looking forward to Siril 1.4 :slight_smile:
