There is a very old bug, the Vignette Stripe doesn't stay where you put it - after SU restart, it will reset its position to the default, whether you lock it or not, it will do the same thing.
And another one (but i think this one may not have a solution), i have two Favorites Palettes that i use in compact mode as toolbars (horizontal stripes, permanently open), every time you minimize and maximize the SU window, these Palettes navigate about 1-2 mm to the left, until eventually you have to move them back..., and so on.
Also, the same behaviour if they are locked or unlocked.
I use mainly SU 2023, in W11.
None of this happened in SU 2022 (and SU 2023), before the LOTT update to be fully compatible with SU 2024.
