I recently upgraded from SumatraPDF v3.1.2 to the current version v3.3.3 (on Windows 10).
Now when zooming, the zoomlevel jumps for example from default (fit to page) to 67%, 75%, adjust to window, 100%, 125%, etc. The Problem is, that ‘adjust to window’ is in my example about 150% - so its much bigger then 100%. Hope you can understand what I mean? So zoom jumps from 75% to 150% and then to 100%.
Here is an example file, where I can reproduce the behavior: https://drive.google.com/file/d/1rU_VW1BrGTWimWYdf2dojnZfVzuAu6mH/view?usp=sharing
My only workaround for now is to switch to single page view.
