Hello again. I tried updating, but I’m still seeing the same issue. I’m now on the latest version of Reaper and Scaler 1.8. I tried AU, VST and VST3 and I get the same behavior. It’s pretty strange because I’m sure that this used to work before.
Edit: Sorry, after updating, I restarted my computer and now everything is working as expected. I thought I only had to restart Reaper, but for some reason I had to reboot the system after the update.
