setting antialiasing to 'false' selects the wrong AdapterINfo #3102
Description
Is your issue REALLY a bug?
- My issue is indeed a bug!
- I am not crazy! I will not fill out this form just to ask a question or request a feature. Pinky promise.
Is there an existing issue for this?
- I have searched the existing issues.
Is this issue related to iced?
- My hardware is compatible and my graphics drivers are up-to-date.
What happened?
This issue was first reported to the halloy project squidowl/halloy#1220
I'm on a setup with 2 GPUs, one intel iGPU, and one NVIDIA dGPU. Ubuntu 25.04.
X and everything is supposed to run on the nvidia.
When starting Halloy, it crashes after selecting the wrong GPU. But the problem disappears if disable completely my intel GPU in the BIOS. I can confirm that it works correctly with either an intel or an nvidia GPU, but it fails when both are available in the machine.

After poking around I found out that disabling the antialiasing provokes the problem. So I reproduced the problem with one of the iced example:
