I have an erratic Problem. Sometimes the Reaper GUI lags periodically as this gif shows:
I use the latest Windows10-Version and an RME-Fireface. The sound is not affected. This occurs with different Reaper Versions. Some plugins-UI get the same lags (e. g. Oeksound Soothe) some are unaffected (Fabfilter, Waves).
The DPC-Latency-Checker shows no noticeable Latencies on my system.
Any hints how to solve this?
