Windows RDP used to be great, but now they figured they'd put animations and transparencies all over the place, so it's become very frustrating to use. Even over a local Gigabit network.
I watched a colleague use VSCode earlier today and was kinda shocked at the amount of pop-ups, and also how they'd cover the active pane, including what the developer was typing.
My attention system isn't built for modern Microsoft apps, I think.
