PETG infill top issues

I've been printing with orca lately @ around 350-600mm/s & 10k accel. Delta 4028 running @ 40-100% depending on layer time. Bridging speed @ 75mm/s CHT Hardened steel nozzle 0.4mm 0.5 linewidth 0.25mm layer height Thick infill bridges ON (default) Idk why the first layer on my infill is never flat, it rises lik in the picture and makes for a terrible top surface

tried with the option off, it was worse. reduced fan speed and it was better. reduce speed to 40mm/s and it was even better. currently at 40mm/s & 12% fan (4028)
