New Install, Black Screen, No Tools, No Images...

[Indeterminate]

Installed GIMP 3.02 on Sequoia 15.4.1 on Mac mini M4, Dell U2724DE at 2560 x 1440 over TB4.
I have a black screen with menus that pull down and operate, but I have only a black screen with a vertical divider bar about 2" from left edge of screen. Opening know good .jpg(s) changes the filename under the menubar, but that is all. Same with File>New, I get a new filename but no image.

I searched the web for similar problems but am not finding anything.

I am new to GIMP and the computer as well (finally upgraded from a 2014 mini running Mojave and ... CS5   ). The Sequoia install is fresh/clean and I have manually moved all my data over. All the apps are also installed fresh. I tried and tried to use Migration Assistant but it brought over 10's of thousands of old detritus, e.g orphaned kexts/plists/etc. from long-gone apps dating back to a 2003 PowerMac G4! :cheapskate:

There is a bug report about this, you could add another report just to keep it fresh in the developers mind(s)

Thanks rich2005.

Meanwhile, I stumbled across the workaround: simply click the green button in the title bar to get to full-screen mode and then everything works. The bug reproduces only if I Quit GIMP while it is in full-screen mode, with the menu bar auto-hiding. If the menu bar is visible while Quitting, GIMP comes up working next time it is opened, regardless of how big the window was at the last Quit.

Seems like devs might have better things to do so I didn't report it. Or maybe I'm projecting and it is me who has better things to do?
