------------------------------------------
Summary: Consecutive window resizes cause a disconnect
Key: GUACAMOLE-1926
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1926
Project: Guacamole
Issue Type: Bug
Components: guacamole
Affects Versions: 1.5.4
Reporter: Stefano Spadola
Attachments: image-2024-02-26-16-37-43-662.png
I think there is a code regression in 1.5.4 although I haven't had a chance to
read the code well.
The problem occurs in 1.5.4 but not in 1.5.2 which I was using before migrating.
The problem occurs during an RDP session, with "display-update" set to true, if
I subsequently resize the window 4/5 times it ends in connection close.
I don't use stock guacamole for the client part (javascript) but I use the
guacamole-common-js libraries to make small customizations.
As regards the js client part, the code is quite simple and is as follows:
{code:java}
const resize_ob = new ResizeObserver((element) => {
clearTimeout(resize);
resize = setTimeout(() => {
....
guacamoleClient.sendSize(width, height);
}, 500);
});{code}
_______
Instead what I have out of the guacd logs is this:
{code:java}
guacd[152]: DEBUG: Server resized display to 1794x993
guacd[152]: DEBUG: Server resized display to 1794x867
guacd[152]: DEBUG: Server resized display to 1794x1006
