Lightburn keeps freezing when 2 windows are open

As the title says, LightBurn keeps freezing and becomes unresponsive every time I open a second window and start doing any kind of work in it. I have to close the program each time to continue.

I’m using an Asus laptop with Windows 11 Pro, 16 GB of RAM, a 4 GB graphics card, and 1 TB of storage. This issue doesn’t happen with any other program I use.

I’m using a 20-watt fiber laser, in case that’s relevant.

It likely is relevant, in this case. The Gweike G2 uses a BSL controller, and we have to use a proprietary library to talk to it. This is a part that we don’t have full control over.

Which version of LightBurn are you using?

Does LightBurn unfreeze if you unplug the laser?
