@g-man @kofa I just opened the following issue

AgX: pivot target output picker not working, if value has been entered manually before

### Is there an existing issue for this? - [x] I checked and did not find my is…sue in the already reported ones ### Describe the bug Some strange behavior of the `pivot target output` picker was originally discovered by @gi-man (see https://discuss.pixls.us/t/blender-agx-in-darktable-proof-of-concept/48697/2433). I can reproduce the issue as follows: * when **resetting** AgX, the `pivot target output` picker works **as intended afterwards** (in my example, it changes the value from 18% to 20,73%) * as soon, as a value **has been manually set** for `pivot target output` (also if I just set it to 18% manually), a click in the picker triggers the measurement (I can see the frame and the “working” toast message), but after the calculation finished, the value remains at 18% (or at any other manually set value). ### Steps to reproduce see description ### Expected behavior The picker should also work, if a value(s) has (have) been set manually before ### Logfile | Screenshot | Screencast _No response_ ### Commit _No response_ ### Where did you obtain darktable from? self compiled ### darktable version 5.3.0~git949.610a6048 ### What OS are you using?
