Timeline lag issues

[Ovidiu B]

I don't know if I'm the only one experiencing this problem or there are others too. From what I noticed after a period of work, PPro becomes very slow, scrolling through the timeline has an annoying lag and I have to restart the application. Today I noticed that this slowdown is due to the Effect Control panel, if I close it the timeline becomes fast again, even faster than after the restart. And another problem I'm experiencing, after applying an effect from the presets, the playback lags when playing. And this problem is solved by closing and opening the effects panel.

System info
    Application: Premiere Pro (Beta) v24.1.0.15
    OS: Windows v10.0.19045, RAM: 95.93 GB GB, CPUs (logical): 16

That is what I have been saying for some weeks; the effect controls panel induces slow playback.

If you make sure no clip is selected in the timeline (as in ECP is empty) playback is normal.

It'd be interesting to know which effects were displayed in the ECP, when you experienced the lag...???

No effects, with effects, makes no difference.
