Hello Maurizio,
Your "Maybe you set some resize mode on the headers, ..." sentence made me =
try QHeaderView.ResizeMode.Fixed value for QHeaderView.setSectionResizeMode=
(),
and that solve the slow jitter problem.
Thanks
Matic

Without any other details it's impossible to help you.
Maybe you set some resize mode on the headers, or used a custom delegate th=
at requires too much time to repaint.
We need some actual code to start with, otherwise nobody could help you.

Maurizio

Is there a way to fix this slow resizing?
