Describe the bug / provide steps to reproduce it

Running zed opens a new window, but its a black rectangle. The mouse cursor changes to an I-beam text cursor in what I guess are the right places, and I can resize it via edges and corners, but it remains a black rectangle.

Environment

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.4 LTS
Release:	22.04
Codename:	jammy

vkcube detects my GPU as:

$ vkcube
Selected GPU 0: Quadro K4000, type: 2

vkcube also runs with these two --gpu_number settings:

$ vkcube --gpu_number 0 --c 50
Selected GPU 0: Quadro K4000, type: 2
$ vkcube --gpu_number 1 --c 50
Selected GPU 1: llvmpipe (LLVM 15.0.7, 256 bits), type: 4

If applicable, add mockups / screenshots to help explain present your vision of the feature

No response

If applicable, attach your Zed.log file to this issue.

At a guess I think this is telling us that although vkcube uses my GPU (see above) zed is failing to use it.
