Serious UI Issue with Patch Selection in Omnisphere 3

[Marsin Na]

Hi,
after upgrading from Omnisphere 2 to 3, I’m getting a strange UI issue in SONAR 8.5 and I’m wondering if anyone else has seen this.

✅ Symptoms (short version)

Mini Browser doesn’t show patches after selecting Directory/Category

Clicking a patch changes the sound, but the patch name doesn’t update

Mouse scroll stops working completely

Only the up/down arrows in the Mini Browser work

Full Browser still works

Everything else (knobs, filters, envelopes, FX, audio) is normal.

✅ Important clue

The issue starts right after I close the UI window of any Omnisphere 3 instance.
It doesn’t matter if I have 1 instance or 6 — closing one window seems to trigger it.

Sometimes everything works perfectly with multiple instances.
Other times it breaks immediately.

✅ My setup

SONAR 8.5

Windows 10

Omnisphere 3 (clean install, authorized)

Omnisphere 2 had zero issues in the exact same setup

✅ Question

Has anyone using SONAR 8.5 seen similar VST UI issues with Omnisphere 3 or other plugins?
Is this a known VST2 event-handling limitation in SONAR, or something that can be worked around?

Thanks!

I suspect that Omnisphere 3 will not be the last plug-in that has compatibility issues with SONAR 8.5.

I saw some issues going on between some older AIR synths and the new Sonar, but those issues seem to have been sorted by one or both parties.

My guess is that the developers of Omnisphere started relying more on Open GL or something similar to render their UI, and that broke compatibility with the old SONAR 8.5. Plug-in compatibility is like a game of Whack-A-Mole, and nobody has been wielding the mallet for SONAR 8.5 for quite some time.
