Hello We are experiencing an issue with Horizon 220.127.116.1151278 and a business application. We are publishing the application on a Windows Server 2019 RDS server. Our users are using the horizon client and the blast protocol to access the application.
However, with this application and horizon, copy/paste works very badly. If the user tries for example to copy several rows in his application to paste them on an Excel local to his workstation, the result is very random...sometimes it works, often the data is incomplete (rows are missing) and sometimes it is the content of a previous copy/paste that is displayed.
I have already tried several times to open an incident to the support, but it accuses the application of being the cause of the problem.
However, the copy/paste works very well with the application locally, with Citrix and with an RDP publication. It is really when using Blast or PCoIP that the problem occurs. We tried several settings in the GPO, the copy/paste works a priori correctly with other applications.
However, the user only copies a limited amount of data which is far below the file copy limits. We don't understand what's going on... We would like to use horizon and publish the application at least in RDP (since the problem doesn't occur with RDP) but horizon doesn't allow to use this protocol with a published application.
If anyone has an idea...
Beside the questions from Felix, please help set the log level to verbose, then collect the logs and send to us.
