reaper dropouts / freezing

[usiname]

Thanks for giving yabridge a shot!

• I read through both the troubleshooting and the known issues sections, and my issue wasn't listed there

Problem description

The issue arises when using Reaper with Native Instruments' sample player, Kompakt (EWQL library) / Kontakt 5. Generally, everything functions well, but when operating with a small block size (e.g., 64), the system occasionally freezes. This behavior can be triggered simply by shaking any GUI element. Increasing the block size to 256, 512, or higher significantly stabilizes the system. However, shaking GUI elements intensely often leads to a dropouts / freeze in Yabridge. The system monitor then shows one of the CPU cores stuck at 100%. Ending the 'yabridge-host.e' process resolves the issue, allowing the project to be reloaded in Reaper. JACK or ALSA makes no difference.

Anything else?

I'll try also low latency kernel and see if the issue appears...

I'm also experiencing a lot of drops on neural plugins. setting a higher block size didn't improve it for me either.
I think it happened after a recent wine update.
It upgraded from reaper 7.20->7.22 and wine-staging 9.15->9.17
I haven't downgraded to verify it yet.

meanwhile I was able to test the low latency kernel and i got the impression that issue is not present anymore. at least shaking any GUI elements (e.g. firefox window) didn't freeze the system...
