The problem is not with the project windows or the mixer, as these can be put full screen and will adapt to whatever resolution you have, but can be a problem with some windows / editors. Quite a bit has changed from 7.5 (and even 9.5): some of those windows are now resizable and can be used on smaller screens.
e.g. the project synchronization setup was too big for such a resolution, now it fits - the Audio Export is now resizable with minimum height being around 630 px (but clicking some options automatically enlarges the window)
I’d advice to check for yourself using the 30 days trial: that way you can see if what you actually use is usable on that resolution. If a function you never use won’t fit, then it’s only virtually an issue, but if you have to struggle with that on a window you use 50 times a day, it becomes a nightmare.
There is no work-around, other than using the keyboard to confirm or navigate, the size is fixed: if one of those windows exceeds the screen-size, the content will be off-screen (most often the OK / Cancel buttons).
