Windows 11 and KB5009566
The release note discusses fixes for several security issues and resolving an issue affecting the Japanese IME publisher. On this subject Microsoft explains
“We have fixed a known issue that affects Japanese input method editors (IMEs). When you use a Japanese IME editor to enter text, the text may appear out of order or the text cursor may move unexpectedly in applications that use the multibyte character set (MBCS). This issue affects Microsoft’s Japanese IME publisher and third-party Japanese IMEs. “
On the other hand KB5009566 is not perfect. It comes with a known and uncorrected problem. Some image editing applications may not render colors correctly on some HDR displays. Curiously, this failure is not new. On the contrary, it is an officially recognized concern. We’re not sure how this cumulative update can make matters worse. The good news is that a fix is in the works. It will be offered in the coming weeks.
