 - fix: Initial window size limits are now properly applied when the window is (almost) larger than the screen.
 - fix: The default choice screen displays previously selected choices in a different color. If you saved at a choice, the colors wouldn't update when loading.
 - fix: Debug adapter: Relative path handling used by breakpoints didn't always work on case-insensitive file systems. 
+- fix: Parts of lines would sometimes be cut off or missing from the text log due to a rounding error.
 
 # v4.9.6
 - fix: File permissions were broken for Linux/Mac builds when building on a file system which doesn't support permissions (e.g. NTFS on Windows)
