Tab title redraw bug

After upgrading XYplorer 24.40 portable to 25.60 portable I notice the following bug: when the mouse arrow moves over a tab, the text of that tab is redrawn incorrectly, like in a broken, extremely pixelated cleartype.
If I downgrade to v24.40, the bug disappears.
I'm using Windows Server 2003, theme "Windows Classic", cleartype enabled, Themes service disabled.

Strange. Nobody else reported this.
1) Are you using any 3rd party Windows skin?
2) Does it also happen in a fresh instance (= with factory defaults)?

Good news. I isolated the problem.
The bug shows up if:
- Cleartype is enabled in the OS, and
- Configuration -> Tabs and Panes -> Tabs -> Visual Style is set to Windows Theme Style
Changing this setting to
XYplorer Archaic Style or
XYplorer Modern Style solves the issue.
Since nobody reported the problem, I guess that it only happens on Windows XP/2003. Sad to see the last good Windows being abandoned.
PD: To answer your questions: I don't use any 3rd party skins; it doesn't happen in a fresh instance unless Visual Style is changed to Windows Theme Style.
PD2: Enabling or disabling the Themes service doesn't make any difference.

Thanks, interesting

But hard to understand: The code used to draw the caption is the same regardless of the "Configuration | Tabs and Panes | Tabs | Visual Style" setting.
Can you show a screenshot of the issue?

Sure. I attached screenshots of before and after changing visual style.

Ah, that's several identical captions printed on top of each other without erasing the previous one first. I should be able to fix that.

I think you should simply set the style to "XYplorer Archaic Style".

Yes. Archaic and Modern work fine. I'm currently using Modern.
