Premiere Pro Timeline Performance Degrade over time. (Most Likely a Ryzen Sys Based Memory Leak?)
using the most up to date premiere version 23.1.0 on windows 11
found that over the past few months my timeline performance was horrible. zooming in. moving clips. all of that. slow. people suggested resetting my layout to default which i did and it worked once or twice but now with the latest update. i found i had to restart all of premiere to stop the lag. then i narrowed it all the way down to a simple sequence being open. as the lag was always exclusive to a sequence. if i swapped to another i hadnt used that much in this session then it would be fine.
so i then checked if closing the sequence. by clicking the x on the name on the sequence panel. and then reopening it via the bin caused all performance issues to dissapear. but over time slowly become more and more laggy until it becomes almost useless.
my speculation is theres a memory leak within sequences that over time slowly caps memory out until lag appears and closing that sequence forces it to re-render and re-"code" if you will. from scratch to open that timeline again. causing the memory leak to vanish and start from scratch.
also the issue may be ryzen specific. as ive been talking to many people on reddit about timeline performance and most of them have ryzen cpus. theres a seperate way that ryzen cpus deal with memory leaks if i recall correctly. where on intel systems the issue wouldnt have the ability to be replicated on an intel based system.
and just to be clear this is not video performance. not playback. simply the UI's Responsiveness. its been an issue for me on ryzen since ive owned ryzen and ive had 3 ryzen systems now. with the bug present on all.
only now the solution of closing and opening the sequence has given me a workaround or a temp fix and maybe even opened my eyes to the route cause
an easy way to reproduce this issue is work with multiple nests. specifically audio nests. multiple audio tracks and a lot of cuts. the software will then start to slow down like usual. but then its like it doesnt stop. the longer the sequence is open the slower it becomes until its reopened
