Hello,
That's not what we would expect. Could you please send us a simple example project we can run "as-is" to reproduce the problem here?
Thanks in advance.

Hi elmec,
This looks like a Firemonkey for C++ Builder bug as I can not reproduce it with a Delphi HD Firemonkey application, which I attach. Could you please add it to
bugzilla? Doing so you'll be identified as the creator of the issue and therefore notified about its evolution.
Thanks in advance.

Not that I can think of for now. The only alternative would be setting BufferedDisplay to false.

Hi elmec,
BTW, this is only a Firemonkey problem, it works fine in VCL. So you could create VCL applications instead.

Hello Narcís ,
Thanks for your advice.
But it's impossible for us to change to VCL,
for we'll go to release our software this end of month...
IF you get to know anything that could help us, please let us know.
Thank you in advance.

Hi elmec,
Did you receive David Berneda's comments about this issue? He suggests a solution in comment 2.

He suggests us to change TScaledLayout to TLayout..which we tried before.
But as a known TScrollPage tool bug, when it is resized,
it needs to remove series of TScrollPage tool, and assign series to it again.
We are afraid that it will slows down the speed by repainting again and again
whenever the form is resized, so we are using the TScaledLayout instead of TLayout
to contain TChart to avoid it resized every time.
