The test case is passing even on my PC with WinCairo WK2 because it has another bug repainting the entire content area by changing selection. Bug 213277 – [WinCairo][WK2] The entire content area is unnecessarily repainted just by clicking a text

Created attachment 402082 [details] test content (abcd) This issue can be reproduced by using alphabet.

Because the extents of glyphs "ab" are overlapped, _cairo_scaled_font_glyph_device_extents returns true for 'overlap_out'. Then, texts "abcd" and "ab" are drawn by using composite_glyphs_via_mask, while a test "cd" is drawn by composite_glyphs without a mask. This causes the tiny difference. I modified _cairo_compositor_glyphs to overwrite 'overlap' to TRUE or FALSE. I confirmed the tiny difference disappeared. diff --git a/src/cairo-compositor.c b/src/cairo-compositor.c index b31413b99..0147ed3bc 100644 --- a/src/cairo-compositor.c +++ b/src/cairo-compositor.c @@ -242,6 +242,7 @@ _cairo_compositor_glyphs (const cairo_compositor_t *compositor, clip, &overlap); if (unlikely (status)) return status; + overlap = TRUE; do { while (compositor->glyphs == NULL)
