The frame flushed the font atlas a second time after drawing, on top of the flush gg.begin already does, so sokol rejected the second sg_update_image of the same frame. The flush now happens once, in gg.begin. Glyphs rasterized during a frame reach the GPU on the next frame. In on-demand refresh mode nothing schedules that frame, so the window kept the stale atlas. A frame that uploads pending glyphs now requests one more paint.
