Using Classic Outlook on Windows for personal email, calendar, and contact management
Same problem for one of my customer in a VDI environment for 100 people (law business), Windows 11, O365 Apps for enterprise version 2306 and NVIDIA Grid T4 with driver version 528.89.
Part of the previous word disappear when typing text. If I stop at the good moment, a part of the word stay "invisible". If I refresh the mail/word (scroll, underline etc..), the word reappear instantly.
Clearly a kind of "refresh" problem like a buggy performance optimizer that refresh the screen "on change" but sometime the optimizer take a "snapshot" before the word is displayed and the screen stay with invisible letters.
