Hi, I often use a company portal based on Apache Guacamole that allows us to connect via RDP (port 3389) to various machines in the company, in fact I do an rdp-over-html5. Starting from version 134 of FF when I connect I find a black screen with the microscopic connection of the machine I am connecting to at the bottom center (obviously unusable). With any other chromium based browser there are no problems. I waited for the FF update to 134.0.1 but the problem persists. This problem has been found on all the PCs I have tested and does not depend on the operating system used (Windows 10/11). Suggestions? Thanks.
