The EditBox input handling is malfunctioning. When typing text such as "test," only "tes" is displayed, with occasional rendering of a small superscript glyph or a single character omission. The last typed character is effectively hidden or not rendered properly. Initial suspicion was related to SpellCheck or custom scripts, but disabling these does not resolve the problem.
P.S: Also I'm having the same issues as Bug #5845 i.e. Ctrl+Backspace does not delete previous word in EditBox. I'm using Windows 10 Enterprise.

P.P.S: O.K. I pinpointed the issue: it only happens when using my font "Source Code Pro Black" "10" "Bold" in the EditBox. Can you please fix this so I can use this font again?! I don't think I had this issue before the latest update.
P.P.P.S: Nevermind I'm using "Source Code Pro" "10" "Bold" and that works, no need to fix anything, thanks anyway!
