Hello,
Used skin – Opus. Versions checked – 12.10, 12.12, 12.16. OS – Windows 7 Pro. Delphi 2010.
The TsTabControl control has several items (tabs) which buttons don't fit completely for the current controls size. As a result – I have two scroll buttons appeared at the left side for the tabs scrolling ('<' and '>', picture problem1.png). Then I'm pressing button '>'. First tab button disappeared, no other changes detected. Pressing button '>' for several times – no changes (picture problem2.png). Trying to press the shown tabs buttons for several times – without success until I pressed a place closer to the most left button. O-o-ops! The tabs buttons are redrawn (picture problem3.png).
The same thing when I'm trying to scroll back left via the left button ('<') but drawn artefacts are slightly different. Scroll to left/right is OK if I'm pressing a tab button which is partly drawn (for example, on problem1.png there is a fourth button which has only first letter drawn; when I'm pressing this fourth button then they scrolled fine, picture problem4.png). Please feel free to ask me any details if needed. Best regards, Sergey
Those are ancient Delphi components. I didn't even know that they are still around.
Yes, these components are quite rare but very useful. I have attached the requested library plus the ToolBar library which used by SpTBXLib.
I can try to make a simple application without SpTBXLib to check whether it is a root cause or not.

Here is a test project which easily reproduces the problem.
For proper work please set SkinDirectory in SkinManager and select, for example, the “Opus” skin.
If there is no skin selected, everything is drawn correctly.
