A few weeks ago, I noticed a sudden degradation in quality when I generate FLUX images with LoRAs.
Normally, the XLabs FLUX Realism LoRA, if configured in a certain way, used to generate images as crisp and beautiful as this one:

I have many other examples of images of this quality, with that LoRA and many others (including LoRAs I trained myself). I have achieved this quality since the first LoRAs for FLUX were released by the community. The quality has not changed since Aug 2024.
However, some time between the end of January and February* the quality suddenly decreased dramatically, despite no changes to my workflow or my Pytorch environment (FWIW configured with Pytorch 2.5.1+CUDA12.4 as I think it produces subtly better images than Pytorch 2.6).
Now, every image generated with a LoRA looks slightly out of focus / more blurred and, in general, not close to the quality I used to achieve.
Again: this is not about the XLabs LoRA in particular. Every LoRA seems to be impacted.
There are a million reasons why the quality of my images might have degraded in my environment, so a systematic troubleshooting is a very time-consuming exercise I postponed so far. However, a brand new ComfyUI installation I created at the end of February showed the same inferior quality, and that made me question if it's really a problem in my system.
Then, today, I saw this comment, mentioning an issue with LoRA quality and WanVideo, so I decided to ask if anybody noticed something slightly off.
I maintained APW for ComfyUI for 2 years now, and I use it on a daily basis to generate images at an industrial scale, usually at 50 steps. I notice changes in quality or behavior immediately, and I am convinced I am not crazy.
Thanks for your help.
*I update ComfyUI (engine, manager, and front end) on a daily basis. If you noticed the same but you update them more infrequently, your timeline might not align with mine.
