02/25/2023, 9:04 PMHi there, I am trying to build similar to https://github.com/InQBarna/TableFixHeaders lib for compose. I have implemented some parts of it with the help of lazyColumn and lazyRow however the horizontal scroll that scrolls the entire content with top headers lags.I want a smooth scroll. Can anyone guide me in the right direction? check out my implementation here with function DrawTableUi https://github.com/youranshul/tableFixheaderCompose/blob/main/app/src/main/java/com/retroent/tablefixheadercompose/drawTableVIew.kt

02/26/2023, 6:01 PM@Petr Laštovička I have not tried with Lazy grid as my problem is not laying out the view but their scroll. Do you really think lazygrid would help?

02/27/2023, 2:21 PMPlease lookup any convos in this slack channel regarding compose perf. pretty much the first thing the compose team will tell you is to test in release builds with minify = true.

02/28/2023, 1:47 PM@Colton Idle I tried with release builds with minify=true but that did not help, however @myanmarking pointing about the recomposition due to xxx.toList() , I fixed that and it did not work but I realized my ListState.firstVisibleItemScrollOffset was causing lots of recomposition. I have found another approach for a workaround though I have some other problems. I will fix a few things and update you guys on the progress and help. Thanks
