Similar to WSLg #877 but now Illegal instruction at address 0x7fed3c8ac259 on Intel Core i7-14700K

Windows Version

Microsoft Windows [Version 10.0.22631.4541]

WSL Version

2.3.26.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.167.4-1

Distro Version

Ubuntu 24.04

Other Software

Inside WSL Ubuntu, GUI apps stopped working after new CPU install.

After several hours of troubleshooting, I determined it's almost the exact problem described at wslg#877 microsoft/wslg#877
(cannot open display: :0, /tmp/.X11-unix empty without symlink)

Except I'm getting "Illegal instruction at address 0x7fed3c8ac259" with a new Intel Core i7-14700K.

I've had to disable the CPU integrated display adapter to get WSLg working again, which is less than ideal, since I generally use both the NVIDIA card and the CPU integrated graphics for separate monitors.

Posting here for others. It's possible this resulted from overclocking configuration, or it's something Intel needs to fix.

Repro Steps

1. Install Intel Core i7-14700K
2. Open WSL Ubuntu
3. Try to run a GUI app

Expected Behavior

GUI app launches

Actual Behavior

$: cannot open display: :0
