bcm: change color chan to RGB24 (thanks p.kosyh) p.kosyh writes: Hello! I finally bought rpi4 4Gb specially for 9front. It seems, that default bpp of framebuffer is 16. I changed it to 24 (via cmdline.txt and config.txt) and found, that rendering is much faster! (May be due removing overheads in 16->24 conversions?) But on rpi4 r and b channels are swapped. So, i changed BGR24 to RGB24 in bcm/screen.c and now it works fine!
