Flicker of a TScrollBar on a TSpTBXGroupBox

[Makhaon]

I have puted TScrollBar and TSpTBXLabel on the TSpTBXGroupBox and TScrollBar has strange flicks when I move mouse over the TScrollBar.
I have added simple test case
test1.zip

Can't reproduce. Are you using the latest version?

Thank you for reply!

Are you using the latest version

Yes, I do. I just re-downloaded the SpTBX and TB2K, patch it for clear experiment. And the flicker still exists. I use Windows 10 and Delphi XE6. I could get a video for you, if it will help. Also Team View access is possible.

Are you still experiencing the flicker with the latest version? In your demo you use the CoolScrollbar unit, try removing it.

HI! Yes, I do. Unfortunately the flicker still exists. I have remove CoolScrollbar. Delphi XE6, Win 10, and your latest original sources.
