Hi Bruno,
(In fact, I have not the latest VCL UI Pack, but one point release before : 11.0.2.0)
In a test project, I can't reproduce the HDPI Text scaling issue. But I can reproduce all other "glitches" in User eXperience : try entering in EditMode, change something then leave editing by clicking another cell in the 4th column (only cells from 4th column are editable)
I sent an email yesterday (not sure if it was delivered because it was sent using a never configured Windows Courrier...) regarding a crash in TAdvStringGrid while deserializing the form DFM : RowHeights : Incorrect Property Value. I circumvent this one by creating the grid by code. You can see it in action by clicking the "Open Broken Form" button. Hope it will crash for you too, I'm totally fuzzed by this one.
What's strange is that this form can be opened by the designer : everything works ok for several "rounds" of tweak the grid / tweak the code / run / test / stop app or kill app by the debugger, ... rinse and repeat. When the RowHeights property appears in the DFM, removing it by hand don't fix the problem.
Please note that I'm using Delphi 11.2 with LSP Patch applied and Navigator plugin installed (from GetIt) I have lots of crashes due to the Navigator plugin but I can't work without it.

Thank you for paying attention to my problems
