Mac Ventura - external monitor - Kitty not showing properly if kitty launch on monitor connected via display-port.

[anieruddha]

Describe the bug Mac I have 3 monitors connected to my laptop using docking station. 1 laptop connected on HDMI & other 2 on DP port. If I launch kitty on monitor connected on HDMI, it works fine. But if I launch kitty on monitor connected on DP port, it just goes blank.

This issue is specific to Mac Ventura. It started after I update mac to latest ventura. It was working on mac before update. My other programs, IDE, iTerm2 working as expected.

To Reproduce Steps to reproduce the behavior:

1. To reproduce, connect external monitor on DisplayPort
2. Launch Kitty on monitor connected on display port
3. See error

Screenshots Monitor connected on DisplayPort

Monitor connected on HDMI

First of all you are running an outdated version of kitty, update.

[anieruddha]

Updated kitty now. Unfortunately same behavior

[kovidgoyal]

Hmm well I dont have the hardware to test this so it's difficult for me to debug. Seems like a driver issue to me. Try reporting it to Apple. kitty has no displayport specific code in it.

[kovidgoyal]

Oh and does moving a kitty window from one monitor to another monitor also crash?

[anieruddha]

Current behavior : when launch kitty on DP monitors, I see screens as shown in first screenshot. If I launch kitty with --debug-input, it print mouse movement & key events. But I dont see anything. Dragging kitty to HDMI monitor, do nothing difference. Same behavior. When launch kitty on HDMI monitor or on laptop screen, I can see terminal window, run commands normally. Once I dragged kitty to DP monitor, it sort of froze. I can't see keys I typed.

I put small script in path which create file & add current timestamp in file. And execute that script from kitty. That script executes whether kitty is on DP monitor or HDMI. So seems kitty is executing command. Only on DP monitor, it not drawing or updating terminal window.

I will reinstall drivers & will update. Thanks for looking into this.

Ah, if the issue is that the window is not being drawn, not that kitty is crashing, then this is likely a duplicate of #3519

Reporting it to Apple is the best way to get it fixed.

I was able to resolve this now. I reinstall displaylink drivers & disable dynamic graphics switching (one of my colleague suggested ). I did that following this post. Restarted mac just to be sure. Now its working. It works with integrated as well as discreet graphics.
