FPS drop when zooming in

Well, my laptop isn't a particularly powerful one (Ryzen 2500U with integrated Vega 8) and while trying to play Factorio on a 4K screen I noticed that the game runs better when camera is zoomed out. This is kinda weird - from my understanding, while zoomed in, the game has to render less items, so FPS should be higher, right? This seems to be clearly a GPU bottleneck, because CPU usage also drops.
I'm curious what is the reason behind this
OS is Fedora Linux 35

What is Settings -> Graphics -> Sprite resolution set to? If "High" (which it looks like from the screenshots), does changing it to "Normal" improve things?

No, changing sprite resolution to Normal doesn't change anything.
It looks like the time is being spent in draw-engine and Flip[off] (whatever that means)

Flip is the time it takes for the rendered picture to be displayed. High values are usually driver/OS issues.
