Performance issues since update to 2026.3.8.0

Performance issues since update to 2026.3.8.0

Since the latest update and the subsequent fix, I have been experiencing severe performance issues with RDP Manager.
As soon as I start an RDP session, it takes approximately 10 seconds for the window to appear. Additionally, I cannot use the manager during that time. When I try to open a second window, the application enters a “Not Responding” state. It then takes another 10 seconds before I can use it again.
I have already configured all performance settings recommended by Devolutions, such as hardware acceleration.
What can be done to resolve this issue?

Exactly the same problems here. I looked for fixes or settings in the forum, and in the end I decided to roll back to 2026.2.19, which is really stable and meets my needs and my colleagues'.

I liked the new interface they created, and I am sure Devolutions has put a lot of effort into this... I hope they can fix all these issues, and in about one or two months I will try the newest version.

Thanks for the info. I just downgraded to 2.19 and its a night and day difference. It works perfect with the older version. Gonna stay here as long as possible :)

Hello

Sorry for the trouble. Clearly it's a bug that's triggered in your environment, at a guess something is blocking while we're loading the Microsoft RDP control. I can't easily reproduce it on my side, so I'm afraid I might need some help from your end to understand what's going on. Before I send some more detailed diagnostic steps, could you answer a few questions about your setup?

  • What's your OS version of the machine running RDM?
  • Is it running locally, or inside a remote session?
  • What kind of workspace do you use (local SQLite, SQL, Devolutions Server...)?
  • Are these "vanilla" RDP sessions or do you have some customization (events, scripts, that kind of thing; direct connection or through a VPN? How is the VPN set up?)?
  • Do you get the same behaviour with a default RDP session to a local host (i.e. just taking the default settings from RDM)?


Please, let me know if something isn't clear or you have further questions, and thank you for your patience

Kind regards,
