On Xfce with compositing off, X11 has no alpha to blend against, so the transparent background came out as a black box around the cat. When a window comes up without an alpha channel, TNCat now cuts the window down to the pixels the drawing covers, using the X11 shape extension, and refreshes that 15 times a second so it follows the animation. A sitting cat in a 120 x 106 window comes out as 96 rectangles over 29 percent of the window, so most of the box is gone. Edges are harder than with a compositor, one bit per pixel, and the log says so and names the Xfce setting that gives smooth ones instead. The image-to-rectangles step is platform independent and folds every device row into its window row, which both halves the rectangle count on a scaled display and keeps a pixel that is opaque in only one of them. xcb and xcb-shape are picked up through pkg-config on Unix and the build still works without them. Opaque mode now paints a neutral card rather than the coat colour. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
