Hello, Commit 90a08cf1fda8eaf4afe98f74a7572fb36b7ef369 from a while ago broke 16bit color drawing in vncv, connecting to a unix: red and blue channels are swapped. Unix uses Xvfb with a 1280x1024x16 screen + x11vnc; 9front screen is XRGB32. ; vncv -v t490sw server version: RFB 003.008 auth type 2 32 bpp, 32 depth, 0x68081828 chan, 1 truecolor, 0 bigendian Specifically: /sys/src/cmd/vnc/color.c:143,146 if(bpp == 32 && v->Pixfmt.bpp == 16){ cvtpixels = cvt16to32; goto Done; } Removing this fixes it. It was necessary for the AMT kvm stuff, but I don't know much about that. What do you think? Thanks, qwx
