Omega slow and unreponsive c/f Nexus and suffers many audio dropouts in music playback

Bug report

Describe the bug

Here is a clear and concise description of what the problem is: After upgrading to Omega, everything in Kodi is very slow.

Expected Behavior

Here is a clear and concise description of what was expected to happen:

I expect the performance to be broadly similar to Nexus.

Actual Behavior

The UI is so unresponsive that Kodi is hard to use. For example, it is very easy to overshoot the intended target of a selection. The RSS feed scroll is noticeably much slower. Worst of all I suffer many audio dropouts when playing music. For example I had 4 within 1 minute of the most recent track I played during which the linked debug log was captured.

Possible Fix

To Reproduce

Steps to reproduce the behavior:

1. Upgrade to Omega
2. Run kodi.
3. Notice the RSS scroll on the home screen.
4. Navigate around with your remote control.
5. Play some music.

Debuglog

The debuglog can be found here: https://paste.kodi.tv/abilegayiq.kodi

The log covers starting Kodi, navigating to select a track to play and playing the track for a short period during which there were 4 dropouts. I had component logging on for smb, audio and audio/video timing when capturing this log.

Additional context or screenshots (if appropriate)

Here is some additional context or explanation that might help:

I am running on an Intel MacMini with 2.6 GHz Dual-Core Intel Core i5, 8GB memory and an Intel Iris 1536 MB GPU. It was perfectly adequate for Nexus.

I am playing ALAC files from 44.1 - 192 kHz.

I had similar performance issues after updating as well. The UI seemed fine to me but videos would constantly stutter and skip. Tried messing with hardware encoding settings but it didn't make a difference. Had to roll back to make video watchable. I was running on Fedora 39 with the Flatpak package from my distro.

I definitely notice audio stuttering issues when playing back WebM videos in Omega. I have 32 GB RAM and 3.6 GHz processor that's nowhere near taxed during playback.
