Windows build of R&Darktable....

No issue I don’t think with the module in fact most of it is display artifact…see the attached video clip…one scroll wheel turn towards higher magnification removes most of it and then the residual color can be muted by the CA module but then not that scrolling back out the display reverts but a bit muted by the CA adjustment. The exported file looks like the magnified one but if people don’t routinely zoom in I guess they could be fooled… I tried Open cl on and off and all of the various scaling methods in preferences…no pattern emerged from that… could just be an anomaly…
