Locking Many Tracks Kills Performance

id like to make note here and say this issue may be linked to the premiere ui lag that i have made a post about previously. as this issue prevails on my machine too. and the machines all suffering from my original bug posting

@jstrawnThe scrubbing performance is much improved thanks.

Locking tracks however still makes the timeline interface overall render much slower when doing operations like zooming, panning, scrolling etc in the timeline panel. Hopefully that can still be improved as well! dragging the scroll/zoom bar goes from 30+FPS to maybe 3FPS. 

The core problem has been fixed in Pr 24.0. Please try a recent version and let us know if it works for you. There may be some related problems remaining, which are currently being worked on.

Has there been any fix?

Here's another video just showing how bad interface performance is once you try to lock out tracks. Makes it very hard to move the playhead or do anything. Scrubbing performacne shouldn't die because you toggled something on the interface.

Here is a video of how bad Premiere reacts to locked tracks and in general. 

It goes from decent CTI performance to about 3fps and this is with a very manageable 4-5 audio tracks locked. Then premeire throws a weird memory error even though I just opened this project and then as I was going to add more audio tracks to show how much worse it gets when you have even more tracks the whole thing froze.
