This the best I could find:
Basically, after your scaling factor and everything is taken into account, you need to have “1080px effective height” for Scrivener windows to properly display.
So if you have 1920x1080 pixels but are running at anything higher than 100%, you will not have enough vertical real estate for some windows to properly display.
I played around with some common hardware screen sizes and put out this table:
[code]1,920 x 1,080 (16:9 aspect ratio)
@ 100% = 1,920 x 1,080 (Meets requirement)
@ 125% = 1,536 x 864 (Does not meet requirement)
@ 150% = 1,280 x 720 (Does not meet requirement)
@ 175% = 1,097 x 617 (Does not meet requirement)
1,920 x 1,200 (16:10 aspect ratio)
@ 100% = 1,920 x 1,200 (Meets requirement)
@ 125% = 1,536 x 960 (Does not meet requirement)
@ 150% = 1,280 x 800 (Does not meet requirement)
@ 175% = 1,097 x 686 (Does not meet requirement)
2,048 x 1,536 (4:3 aspect ratio)
@ 100% = 2,048 x 1,536 (Meets requirement)
@ 125% = 1,638 x 1,229 (Meets requirement)
@ 150% = 1,365 x 1,024 (Does not meet requirement)
@ 175% = 1,170 x 878 (Does not meet requirement)
2,160 x 1,440 (3:2 aspect ratio)
@ 100% = 2,160 x 1,440 (Meets requirement)
@ 125% = 1,728 x 1,152 (Meets requirement)
@ 150% = 1,440 x 960 (Does not meet requirement)

@ 150% = 1,707 x 960 (Does not meet requirement)
@ 175% = 1,463 x 823 (Does not meet requirement)
3,440 x 1,440 (21:9 aspect ratio)
@ 100% = 3,440 x 1,440 (Meets requirement)

3,840 x 2,160 (16:9 aspect ratio)
@ 100% = 3,840 x 2,160 (Meets requirement)
@ 125% = 3,072 x 1,728 (Meets requirement)
@ 150% = 2,560 x 1,440 (Meets requirement)
@ 175% = 2,194 x 1,234 (Meets requirement)[/code]
