Supports XP or later. Hunk 9 succeeded at offset 2 lines. Perhaps a race with the first thread and the update message? There are also some issues with VNC viewer - every now and then it won't refresh on connect.
This wasn't the case prior to the patch - perhaps another interaction with the update message. Unsolicited updates and occasional refresh problems were among the issues I fixed. From my notes: "While debugging, I noticed that the display was not correctly updated when I filled it with black, although it worked well for other fill colors. This was because the CRC values had been cleared in the recent resize, so rfb.
I fixed the problem by adding an invalid variable in rfb. I'll switch over to head of trunk to do follow-up dev on this code. My bad for not checking the patch against it. I agree, TX of screen updates needs a bit of followup work. We should honor the order of client request vs. I'll look into that. I tested the code with TigerVNC also, rudimentary tests showed it behaving ok.
Admittedly, didn't test it very thoroughly. It seemed to me that the CRC variation here would produce non-zero results for all black data, but I haven't validated that. Comment 6 marko UTC Created attachment [details] svn diff output of the relevant changes; ver2 Here's an updated version of the patch, which includes additional performance fixes. I incorporated Henrik's changes from the pointed diff; the most important performance improvement from there was the fact that the server would not send an update until client requests one.
I also reduced the amount of memory allocated for CRC buffers. It was computed slightly incorrectly, but ended up allocating 32 times too much memory. Behaviour changes are now that a support RFB protocol versions 3. Comment 7 marko UTC Created attachment [details] svn diff output of the relevant changes; ver3 Modified to make the server more responsive.
Reception of client update request wakes writer thread immediately, instead of using timer only for the wakeup. With an immediate wakeup, you rely on the client to limit the frame rate. Yet to try ver3 but am interested to see if clients are pacing the requests.
Comment 10 Peter Grehan UTC v3 works great and has very snappy mouse-tracking, but the downside is it uses 8.
