I'm running into a problem where a visible LP MB (L-Phase Multiband) plugin starves the graphics on other visible plugins. The graphics freezes on the other plugins. Anyone else seeing this?  This is with Sonar Platinum 2017.01.
 
Setup:
- Single stereo audio track (from an imported pre-mastered mix).  48kHz.
- One plugin on the stereo track and one plugin on the master bus.
- LP MB on the master bus.
- Opened and pinned one of the plugins (from UAD).  Opened the LP MB.  Now two plugin windows are visible.
- Played the track.  
Symptom: The live graphics on the visible UAD plugin stops.  Expected to see graphics activity on both plugs.
 
I tried removing the UADs and added the Cakewalk PC4K compressor to the master bus using Pro-Channel.  The live graphics stops on the PC4K too.  It doesn't appear to be UAD specific.
 
It looks like the LP MP is starving the graphics on the other plugs.  Minimizing the LP MB window doesn't fix the issue.  Closing the LP MP window solves the issue.
 
NOTE:  I ran something called  "Geeks3D GPU Caps Viewer". Sure enough, the GPU load jumps from nearly 1% to ~80% when the LP MB window is open. The general consensus is that Sonar doesn't need a high-performance GPU.  Has that changed?
 
See system specs below.  The graphics card is an older ATI Radeon HD4650, but this has never been an issue. Drivers are up to date.  Running OpenGL 3.3   I also set the LP MB refresh to the lowest setting.  
 
Any suggestions?
 
Thanks!
 
P.S. Noticed the track view slows to a crawl too.  The level meters are fine.
 
edit: Clarification of familiar "LP MB" name vs the new rebranded name by Cakewalk last week.

I have similar issues with it, too. The now time stops moving, too.

i can't find the post now, but there's some setting to disable opengl to resolve graphics issues, i think it was in one of the l-phase threads
good luck

Thanks pwalpwal.  I'll try a more extensive forum search tomorrow.  It's getting late here on the US west coast.

I had no idea what plugin you were talking about.  The name if we are talking about it is LP-MB.

The name is as I said. L-Phase is referring to the series. I'm not sure it has any meaning except in the context of that thread. If you DL them LP MB and LP EQ is what you install.

Thanks pwalpwal and others. The information in that post fixed the problem.  
 
Using the instructions in http://forum.cakewalk.com/FindPost/3555087,  I changed the setting of enableOpenGL="1"  to enableOpenGL="0".  This had to be done in both LPEQ.cws and LPMB.cwf  files.
 
P.S. Edited my original post to clarify the familiar "LP MB" naming vs the newly rebranded name.
