Before 2026.3, the default when using a HiDPI display with for example 200% scaling (my external screen) or 166% scaling (my laptop screen) and connecting to a remote desktop machine (RDP), was that it would render the remote machine with 100% scaling, but upscale that according to my clients scaling settings.
That would lead to the display being somewhat blurry, but showing all content with the correct size and rendering really fast as it didn't need to fetch 4 times the amount of data to be able to render it pixel perfect on my screen with 200% scaling.
In practically all my usage, this is the perfect balance between speed and quality (mostly preferring speed I guess, but still), so I was quite disappointed when it now can't do that any more.
In 2026.3.0.5, it renders the remote machine with the same scaling as my client by default (even though the settings are set to the same values as before: 100%), which looks quite good but is much slower, and no matter what I set the settings in General->Display->Scaling to, it seems to be impossible to make it behave like it did by default in 2026.2.
I'm using Ubuntu 26.04 with Gnome/Wayland
