Help removing white pixels at seams of modular assets

I am building a city using some modular assets, i did not use the snapping feature initially and a few of my assets are 0.000X values off in rotation and transform which is unusual since my transform units were set to be 90 degrees and 100 units , however i did fix them and created a test area with perfectly set rotations/transforms using snapping but these white pixels still show up and are most noticeable during movement. Has anyone come across this before? what steps am i missing to correct this? I initially thought i wasn’t connecting the assets correctly and the sky sphere was “bleeding” through the gaps, the white pixels aren’t usually as uniform as in the screenshot, sometimes its just a few odd pixels here and there. Please help me diagnose this issue :’)
