I've been experiencing some interesting behavior and crashes ever since updating to 4.6. Whenever I (as the DM) open an image, I start getting periodic (every couple seconds or so) mouse freezes that make the game unplayable. On occasion, I also get a low USB controller resources notification or even experience a full crash/restart of my system's USB controller.
I did some digging through event viewer and found that my audio controller/interface (Focusright Scarlett 18i20 gen3) appears to be the device that is actually crashing, and when it goes down it seems to sometimes take USB on the whole with it.
I can also test some other troubleshooting options upon request, as my system setup is a bit unusual, particularly with regard to audio. The typical audio chain for the system in question is as follows: Windows > VB Matrix (virtual audio routing software) > Focusrite Scarlett 18i20 (via ASIO) > speakers/headphone/etc.
Some troubleshooting steps I've taken so far and the outcomes I've found:
Updated audio interface driver: no noticeable change in behavior
Turn off the audio interface: seems to prevent the instability when loading images in FG so far, but it's far from ideal to play without sound when we coordinate via video chat and I've only been able to test with one client connected.
Uncheck "Sound Enable" under Options > Game in Fantasy Grounds: seems to be working so far, but I've only been able to test with one client connected.
Removing VB Audio Matrix from the audio chain doesn't appear to have any noticeable impact, but I figured I should disclose its presence for completeness.
Attempts to reproduce the issue were done using the image "Storm-Giants.webp" from the purchased "Storm King's Thunder" module in the FG store to ensure reproducibility by the devs in the event that you want/need to dig deeper on your end.
Potentially relevant hardware used to test:
CPU: AMD 5950x
Memory: 128GB DDR4
Operating system: Windows 11 Pro, build 23H2
Audio Device: Focusright Scarlett 18i20 - firmware 1644, driver 4.124.3, connected via USB-C
GPU: nVidia RTX3090, driver 566.36
More hardware info, logs, and troubleshooting available upon request.
