But only darktable is doing it, so there must be some kind of connection.

I initially was ready to lay this issue at the feet of the OS / window manager (dwm.exe in Windows, IIRC) instead of darktable since that’s what manages window placement and state. It’s the only app where I’ve had this issue. After reconnecting, I’ve been unable to get darktable to start maximized on the external / primary monitor. Best I can recall, it started after I disconnected the laptop from its dock (including external / primary monitor) and then used darktable on the panel. Whether or not it started precisely after the upgrade, I can’t say. Uygulama ayrca Windows 8 ve Windows 8.1 iin kullanlabilir. This wasn’t happening before and I’ve also upgraded to 3.8.1. What to do with dialog saying darktable can t be opened because it was not downloaded from. But if I shut it down maximized, it starts on the secondary monitor as defined in Windows (which is my laptop’s attached display). darktable v4.0.0 darktable 64-bit Windows Installer 107.5 MB v4.0.0 darktable macOS (DMG) 91.2 MB v3.8.1 darktable 64-bit Windows Installer 113.5 MB. If I restore (normalize / free floating window) darktable, move it to the primary monitor and then without maximizing shut it down, it’ll start back up normalized on the primary monitor.

Here darktable3.8. is the downloaded file name. Per above link - FWIW, I’m seeing the same thing basically, on Windows 11, latest release, fully patched. Now open the terminal app (ctrl+alt+t) and run below commands one by one to install Darktable.
