Callstack at segfault
Test project |

I suspect though, it's a more common bug, related not only to fast line series, but to any series transparency. Hello Vsevolod V Gromov,
Unfortunately, we can't reproduce the problem you are experiencing, using a simple code as next in latest TeeChart Pro VCL/FMX 2015
void __fastcall TForm1::FormCreate(TObject *Sender)
{
Series1->FillSampleValues(10);
Series1->Pen->Width = 3;
Series1->Transparency = TTeeTransparency(50);
}
Could you attach a simple project where the problem appears?

Simple test project, I ran it both, on Android emulators and real hardware, as soon as "Transparency" button is clicked, AV occurred.
software used:
C++Builder XE7 Upd1 Version 21.0.17707.5020

TeeChart Full Source 2015.14.150120,
re-built from source to accomodate Android hotfix.
