uVNCs problem connecting to TigerVNC-Server

Postby GustelDE » 2020-12-22 19:18

Hi,

we encounter strong problems with uVNC1.3.2 connecting to current TigerVNC-Servers.
The problem was posted on TigerVNC but they told me, its a bug within uVNC: "FramebufferUpdateRequest"

I've installed 1.3.2 here and done some testing. Unfortunately there seems to be some bugs in UltraVNC when it talks to TigerVNC. I can see it spamming FramebufferUpdateRequest messages constantly, some graphical glitches, and the invalid data it complains about is not seen in the protocol dump.

So unfortunately these do look like UltraVNC bugs from our point of view. That means there isn't much we can do about them, so I'll have to direct you to file a bug with them. Feel free to cross reference things here.

Maybe you can look into this issue?
Thanks

Looks like rfbEncodingExtDesktopSize protocol is different implemented.

Hi, here there is a different issue concerning tigerVNC and UltraVNC 1.3.2 standard release: "Attempted to configure an invalid screen layout" when connecting to a UltraVNC server. Fortunately, with the special build you attached above I am able to connect to a Win7 PC running UltraVNC server 1.3.2 from a Linux desktop running tigerVNC 1.10.1. Thank you.

I still need to merge the changes in an official build.
There were also clipboard issue's.
