Log spam

[ChromaPIE]

Client log spams [Render thread/WARN]: [REI] Screen com.lowdragmc.lowdraglib.gui.modular.ModularUIGuiContainer did not render background and foreground! This might cause rendering issues! and neither E nor ESC quits the GUI but only results in a darker background so i gotta use the FTBQuests button to bug out, otherwise i might have to restart the whole game.

I also got Flow in my current instance, which could be a problem causing the issue.

The log seemed to be completely normal but let me know if it's necessary to have the whole log.
