The current implementation of the glyph cache deals with atlases by padding them with 1 pixel at the beginning, at the end, and between each glyph. That's cool and all, however, there's a very subtle problem with this approach: the contents of the atlas are garbage, so this padding is filled with garbage memory! Rework the Vulkan glyph cache to draw each and every glyph in a surface that has 1 pixel border of padding around it. Ensure the surface is completely black by drawing a rectangle before handing it to Pango to draw the glyph. Update tx and ty to pick the texture position adjusted to the 1 pixel padding. The atlas now starts at position (0, 0), since each glyph individually contains its own padding. To improve legibility, add a PADDING define and use it everywhere. |
