Repeater uses javascript array as model, Creates performance issues in Qt 5.12

[MohanSathiyam]

My project code used Qt version 5.12 and IMX 587 processor built on my target device. Here, I am facing some performance issues because the repeater uses the javascript array model, then whenever any item have changes, the whole model is reset and the repeater redraw all items. This issue has been already asked in this link Please see check this link(https://stackoverflow.com/questions/77330573/repeater-model-very-slow-when-copying-an-item/77370504#77370504)

My same project code is flashed in updated Processor version IMX 8 target device and also updated Qt version 6.4. In this device, I couldn't see this performance issue.

So, If I updated my qt version from 5.12 to 6.4 in IMX 587 processor target device, Is resolved this performance issue?

Since, tried to change old code that is big complex one.

Thanks Advance
