I retested this with the current MSW build. A temporary RichTextCtrlTestCase probe created a single 65,536-character wxRichTextCtrl plain-text run, rendered the buffer into a wxMemoryDC, and verified that non-background pixels were painted.

The focused run passed with test_gui.exe RichTextCtrlTestCase -c LongPlainTextRendering on Windows 11. I don't see a remaining reproducible failure in the current tree, so this appears to have already been fixed.

Thanks a lot for taking time to test this (and other) issues, this is much appreciated (even if I'm not going to retype this comment for all the other ones)!

Closing as fixed based on the comment above.
