Issue Description
As soon as I click generate it starts and runs through the generation progress bar normaly, but: The preview is just grey with sometimes just some colord little artifacts in it. When generation has finished the saved image is just black. Also about 30% of the time my gpu driver runs into driver timeout. This happens 100% of the time.
The issue happens on a new installation of sd.next. It happens consistently even after reinstalling. It happens with multible models(dreamshaper_8, sd_xl_base_1.0, juggernautXL_juggXIByRundiffusion).
