If it covers everything you need, you might try EVT_STC_UPDATEUI
instead of EVT_STC_STYLENEEDED. It's worked for me in the past.

This works very nicely, with one exception:
If the window containing the Scintilla control is partly off the screen,
the content doesn't get repainted properly: E.g. when moving some other
window across the Scintilla control, the content of that other window
appears in the text area of the Scintilla control. If I move the Scintilla
control back into the middle of the screen, until it's fully visible, the
repainting works fine.
This behaviour is definitely connected to the STYLENEEDED handler. If I
remove it, everything is OK.
When some actions (such as adding markers) are performed inside a
notification handler there can be some confusion about the area being
redrawn leading to this sort of problem. This has been fixed for
native Windows in 1.67 but I don't think the changes have been
implemented in wxStyledTextCtrl and may be difficult there. This was
discussed in November with subjects "Markers & Lexing" and "Paint
region". Try removing your OnChange handler.
