Did a few tests here, I know the common solution by switch to Not applied or Topmost surface but that only works for text no larger than size 12.
Not perfect but better, this is a test with size 16 text added just in Bambu Studio. Then click the text object increase the wall. There is limitation but this already minimize the layer before the text artifacts.
Ok now, that improved but we can workaround it more by increasing the wall loops for the bottom object by 1 wall. (If you have develop mode on, turn on Interface shells - this way you don’t need to touch the wall loops for the base object; pretty much skip below)
Here is the final result in GIF.
This method don’t need to workaround fix from Fusion or any other CAD softwares.
