Default Mojave: Video Judder/Dropped Frames When Certain Plugins Selected in FX Chain

I've been using Reaper for audio post projects for several years with great success. Recently I upgraded my main workstation from a 2011 MacBook Pro to a 2018 MacBook Pro, which came pre-installed with Mojave. I am aware that Mojave is not currently officially supported for Reaper, but I had no choice but to dive in and start working on audio post for a television series. At this point I am guessing that official Mojave support is not too far in the future.

I am experiencing video judder/dropped frames when I have any FX Chain open and I select certain plugins. For example, when I select plugins by Slate Digital, video playback is without issue. But when I select plugins by Sonnox, I experience judder/dropped frames. When no FX Chain is open, video playback is also without issue.


MacBook Pro (15-inch, 2018)
Processor: 2.9 GHz Intel Core i9
Memory: 32 GB 2400 MHz DDR4
Storage: 1 TB APPLE SSD
Graphics: Radeon Pro Vega 16 4080 MB
Intel UHD Graphics 630 1536 MB
macOS Mojave 10.14.3


Length: 44:22.660
Video: 1280x720@23.98fps, Aspect=1.00, Decoding format=I420/YV12
Audio: 48000Hz 2ch 32bps

Using VLC decoder (v3.0.x)
Video: 1280x720, h264, 23.98fps
Audio: 48000hz, 32bps, 2ch, mp4a

Loaded from: /Applications/VLC.app

48 kHz, 24-bit

I am using Reaper v5.965/64

The situation is workable, but I thought I would create a thread to see if others are experiencing this issue or if there is anything that I can try on my end to resolve it. Any suggestions would be greatly appreciated.
