What happen to EoR?

@Ptirodaktill If I were you, I would test

  • putting EoR on 0 - 9
  • making RMB hold spam EoR button (or maybe even RMB itself if we leave EoR on RMB)

You can use https://github.com/kowariantny/GDAutocaster/raw/master/GDAutocaster.exe for that
I’ve tested and EoR is fluent then and you should never need to re-press+hold RMB again if your issue is the same as quoted one.
If EoR is on 1 then config (GDAutocaster.ini) would be

[general]
suspend_key=Tab

[periodic casts]
cast1=RButton:1

The button is spammed with 1 press / 100 ms frequency by default.
