Continuous window updates while unfocused

[AnActualEmerald]

Hi there! I'm trying to make a Tauri app with a window that goes transparent when it loses focus. I've been trying for a while to fix a problem I've been having when the window goes into the background where it seems like it stops getting redrawn as often, leading to this effect as the UI animates out:

The window also doesn't actually become transparent until a few seconds after. I've looked for a setting similar to Bevy's UpdateMode, but haven't been able to find anything. I've also tried setting DeviceEventFilter to Never but it didn't seem to have any effect on how the window itself is updated.

TLDR I need the window to run in real-time while unfocused. Any suggestions?
