Michael Jumper commented on GUACAMOLE-739:
------------------------------------------

This is not a bug; the 256K limit on clipboard size is intentional. See:

... the remote session appears to have a character limit as apposed to the previous version.

The 256K limit has actually been in place for roughly five years.

>             Project: Guacamole
>          Issue Type: Bug
>          Components: guacamole, guacamole-client
>    Affects Versions: 1.0.0
>         Environment: Guacamole Host: Ubuntu Server 18.04
> Hardware: 2 Cores & 4GB RAM
> Guac Client: 1.0.0 Release
> Guac Server: 1.0.0 Release
> Tested on Chrome 72.0.3626.109 64-bit, Windows 10 Professional
>            Reporter: Gary Miller
>            Priority: Minor
>
> When attempting to use the new clipboard API, copying and pasting from the clipboard in the remote session appears to have a character limit as apposed to the previous version. To test this I created a text document and continuously filled the file until I got to the point in which the clip board functionality ceased. 
>  
> Based on my testing, the clipboard would not copy text after the selection content exceeds around 262,000 characters, I removed /r & /n characters just to eliminate the possibility of the bug being related to new lines specifically and I can confirm that this issue occurs even if a single line exceeds the aforementioned value.
