RGB-Curve bug - DT 4.5 1308 & 1401

hello

could it be that there is a bug in the “RGB-Curve” module?

if you create a simple curve and then click on “compress history stack” on the left, the RGB curve loses its function.

the “pixel-workflow” does not play a role.

happens on my laptop as well as on my PC.

greetings

Not reproducible with my macOS build of current master. So please give your steps to reproduce that behaviour…

I reproduced this problem on my Windows 11 computer with the latest weekly build from @wpferguson. I opened a raw file and adjusted the curve in RGB curve. I then compressed the history stack and my RGB curve adjustment disappeared. There definitely seems to be a bug here.

Not able to reproduce on Linux / Ubuntu 22.04, darktable 4.5.0+1394~g269e57434d.
It may help if you give detailed step-by-step instructions on how to reproduce the issue, and/or if you can share an affected raw image with corresponding sidecar file (xmp).

Expected, there was a transient issue fixed in DT 4.5 1402.

here is the hardware info from my laptop (Win 10).


I can’t get to my PC at the moment.

but the pc is equipped with a mainboard from gigabyte, an i5 4690s, a gtx 950 and windows 10 pro.
