Created attachment 63063 [details] Full backtrace I'm getting an assert on running gtk3-demo with wayland: gtk3-demo: cairo-error.c:68: _cairo_error: Assertion `(status != CAIRO_STATUS_SUCCESS && status < CAIRO_STATUS_LAST_STATUS)' failed. The relevant part of the backtrace: #5 0x00007ffff776373d in _cairo_set_error (cr=0x6dc5c0, status=32767) at cairo.c:180 #6 0x00007ffff7765e9e in cairo_show_glyphs (cr=0x6dc5c0, glyphs=0x7fffffffa660, num_glyphs=5) at cairo.c:3317 #7 0x00007ffff7f8d019 in pango_cairo_renderer_show_text_glyphs (renderer=0x750030, text=0x0, text_len=0, glyphs=0x6d79a0, clusters=0x0, num_clusters=0, backward=0, font=0x4971f0, x=8192, y=13312) at pangocairo-render.c:367 #8 0x00007ffff7f8d0a6 in pango_cairo_renderer_draw_glyphs (renderer=0x750030, font=0x4971f0, glyphs=0x6d79a0, x=8192, y=13312) at pangocairo-render.c:383 I'm attaching the full backtrace. After tracing a bit, the issue is originated by cairo-image-compositor.c:composite_glyphs not initializing cairo_status_t, so it may get a random value.
