This series solves this problem by fixing the separation between the server surface dimensions (which are important for dirty bitmap tracking) and the client desktop size (which is what the client actually renders). Daniel P. Berrangé (4): ui: add more trace points for VNC client/server messages ui: avoid sending framebuffer updates outside client desktop bounds ui: use client width/height in WMVi message ui: honour the actual guest display dimensions without rounding ui/trace-events | 16 ++++++++++++++++ ui/vnc-jobs.c | 44 ++++++++++++++++++++++++++++++++++++++++---- ui/vnc.c | 48 ++++++++++++++++++++++++++++++++++++++++-------- ui/vnc.h | 1 + 4 files changed, 97 insertions(+), 12 deletions(-)
