Flux Dev8

I'm having an issue using FLUX.1-dev8 in ComfyUI.

Whenever I run a simple txt2img or img2img workflow, I get conditioning shape mismatch errors during sampling.

Errors:

• "size mismatch for shared.weight (256384x4096 → 32128x4096)"
• "mat1 and mat2 shapes cannot be multiplied (154x2048 and 4096x3072)"

It happens whenever any non-FLUX text encoder is used (CLIPTextEncode, DualCLIPLoader, etc.). The model only works if all conditioning nodes are FLUX-native, and even then the workflow is very sensitive.

Could you clarify:

1. Which text encoder nodes are officially supported for FLUX.1-dev8?
2. Is there a recommended minimal workflow?
3. Can ComfyUI show a warning when incompatible encoders are used?

Thank you!
