2025.32460 - Spectrum TOP acting strange

Bugs

Touchdesigner2025.32460

Windows 11

See attached video - at 0:47 the issue becomes visible

I updated my graphics drivers and the problem remains.
The problem happens on Mac Arm also.

I have never used the spectrum TOP before So I have no idea if this is a new or old bug.

It is as if the inverse fft is not normalized - or rather, it normalizes randomly and unpredictably.
Sometimes it looks as expected. But if the node is copy pasted, or connected to a null or out-TOP etc, it stops or starts being normalized and can randomly switch between normalized and not normalized.

the issue happens randomly when fft → inverse fft

It happens reliably if you middle mouse click any operator - and the Probe in GPU-mode breaks it.. somehow

Hey @simonryden2 ,

Thanks for the detailed report and steps for reproducing. This does look like unintended behavior and has been logged to be looked at by a dev soon.

Thanks,
