It happens since v. 7 especially with Waves, sometimes with Arturia too (both VIs and FX), plugins open with a completely empty interface. No matter what I do, click, etc. Tried reinstalling, changing some preferences, nothing changes. It happens with both VST and AU. VEP 7.0.834 on Macpro running MacOS 10.14.4 (Mojave).
Anyone else has this problem ?
