As we have discussed previously the display must support the minimum recommended screen resolution 1080 px at 100% scaling. We cannot match the full compile dialog size and settings on a tablet size screens.We might search for optimizations here, but not in the first official release.
The recommended vertical resolution is one more time 1080px at 100% scaling. If you use 150% scaling you end up with 720pts, which is not enough and we do not have the resources to deal with this at the moment. Scrivener is designed as a desktop application not for pocket size PCs/tablets which are quite popular among many. Scrivener for Mac also does not run properly on a 720pts display either.
Reducing the Scrivener menu & windows font size is probably the best workaround at the moment if you have this problem. You can also reduce the scaling of your current monitor or use a bigger monitor. You should not expect miracles buying a small monitor to fit big windows with large fonts, because your eyes hurt using small fonts. If your eyes hurt with small fonts, avoid buying low resolution and small screens.
We are aware of the issue, and this has been discussed multiple times in the forum under different threads.
