The issue with the build 4.9.0+442 is that side panels, which I think are there, are not visible neither in lighttable nor in darkroom.
Build +419 is working as expected, did not try the ones between this one and the new one.
Open CL active or not does not change behaviour.
iMac intel i7 OS 14.6.1
Any other user try this build on other systems?
The fix is ready and will most likely be merged today: restore proper display of modules in sidebars by ralfbrown · Pull Request #17443 · darktable-org/darktable (github.com)
Great, thank you!
OpenCL is used for image processing only, it does not influence the UI.
