Current Behavior

After an OBS restart, a source mirror (of a camera) with virtual greenscreen filter applied is still present in the filter list and enabled with "quality" selected, but doesn't actually apply the greenscreen effect at all, until you go into the filter and toggle the dropdown value to performance, then it becomes re-enabled. It appears to forget, or perhaps has a failure to enable the virtual greenscreen filter properly after the restart.

Expected Behavior

At the point of restarting OBS, the source mirror should retain the virtual greenscreen effect that was previously applied, without the need to open the filter and toggle the quality/performance mode.

Steps to Reproduce the Bug

1. Add video capture device
2. Add a Source Mirror source
3. Add the virtual green screen effect to that source mirror, set it to "quality" mode. Behaviour as expected.
4. Close OBS and reopen it.
5. The source mirror greenscreen filter is present in the filter list and enabled but doesn't actually apply the greenscreen effect until you go into the filter and toggle the dropdown value to performance, then it becomes re-enabled.

Any additional Information we need to know?

Confirmed

Problem is not tied to Source Mirror, but any source that can have 0x0 as resolution when it is created.

In case this helps, when running obs from a shell I get this error message :
