I tested this quickly last night with VcXsrv, and it=CA=BCs utterly broken with emacs-26 built for GTK when using double buffering: the entire text area of the initial frame never gets updated. With lucid it=CA=BCs slightly better in that half the frame gets refreshed. That does suggest that the bug is in emacs (especially since VcXsrv is essentially xorg recompiled for Windows). Initial debugging showed that the appropriated XDBE calls are being made, so perhaps the initial setup of the frame is at fault. More debugging this weekend, I hope. Robert
