High CPU usage since update to Version
Hello
I've made a fix for this. I haven't been able to reproduce the issue on my side because I don't have a matching test environment, but I'm confident the fix is correct.
That will be available in the next version of RDM (2025.1.31).
Once the new version is available and installed, you'll need to navigate to File > Settings > Performance. Under the heading "Avalonia", uncheck all the options except "Enable redirection surface composition mode" (see screenshot below); save the changes and then relaunch RDM.

Thanks for your patience. In the meantime if you have other question or comments please don't hesitate to post back.
Kind regards,

We had the same problem where we experienced RDM used up to 30% cpu.
After updating and following this fix, we are now below 2%.
Thank you very much for your help
