Audio dropouts when nudging notes [in 2016.05 update]

I installed the latest update (2016.05) this morning.
 
Ever since, whenever I nudge notes in the piano roll during playback, the audio (not just for that track, but for all tracks) is interrupted, causing a drop-out.
 
Is anyone else experiencing this?
 
Is there a fix?

I am finding I am also getting interruptions in audio playback when doing any of the following:
 
1) splitting clips
2) dragging notes in the piano roll
3) dragging clips in the track view
 
So, it seems that the audio engine is getting interrupted every time editing happens.

I didn't have this problem prior to this update.
 
Audio latency is 11.6 ms, which is what I've used for years.  CPU usage is low (9%), so I know the soft synths are "pushing it".  I also get the same problems on a brand new project.
 
Is anyone else having more interruptions in playback with the latest version?
 
 

Currently my Mixing Latency settings are these:
 
Buffers in Playback Queue: 2
Buffer Size: 11.6 ms / 512 samples
Effective latency at 44kHz/stereo: 11.6 ms
 
If I increase the number of buffers to 3, the effective latency doubles (to 23.2 ms), which is not desirable.  I cannot reduce the number of buffers to 1.
 

I had this problem some time ago and I solved it as follows:
 
Edit/Preferences > Audio - Sync and Caching
 
Under the heading File System, there is:
Enable Read Caching and Enable Write Caching
 
I enabled one of these and it solved the problem.
Try them, see if it solves the problem for you.
 
Thanks to your posting, I notice suddenly BOTH ARE DISABLED AGAIN!
But the reason in my case is probably because I recently deleted the aud.ini file.
I'll have to try both myself again.

I keep Sonar updated regularly, so I updated from whatever version was prior to 2016.05.  Was it 2016.04? 
 
I've run 2 different latency monitors and one of them is Resplendence.  Both say my system is suitable for real-time audio streaming without dropouts.  Average latency is around 150 microseconds, and peak is 252, which isn't reached very often.  When I start Sonar, and play my project, avg latency is around 175 microseconds, and peak is 298.
 
I think the hardware is fine, since I didn't have these frequent dropouts prior to 2016.05.  Nothing else in my system changed (except for the usual monthly Windows updates).  I noticed the dropouts immediately after updating to 2016.05.
