windows apps not opening with two monitors enabled

[rkunschke]

I've encountered a strange behavior on my multimonitor setup. I am on nixos and using it like mentioned in the readme on my flake.

Freerdp is only able to open apps when there is only one monitor enabled. As soon as I enable the second one the winapps command is just exiting like instant and no window opens. Also nothing seems to be unusual is in the logs:

This is just the same output as if it had worked i think. Enabling/Disabling multimon makes no difference at all. I've tried freerdp-git from a arch-distrobox and that makes no difference as well.

I know there are problems with multiple monitors but I thought they were about black screens and not about no window opening at all.

I am having the same problem on my Arch.
Wİndows app works fine but other apps exit instantly

Seems like there is an issue with the detection of the available monitors.
By using the multimon config and adding the monitors flag to the rdp command, I was able to make it somewhat work:

RDP_FLAGS="/monitors:0 /cert:tofu /sound /microphone"
MULTIMON="true"
