Yes, just noticed this today. There is a warning in the release notes:
In order to solve some highlighting text bugs, the use of GDI+ text rendering has been revised and improved. This may lead to small pixel shifts that normally will not be noticeable, and may affect any objects that use text rendering. Applications that have tightly packed text-information may have to be re-aligned in order to adjust appearance
It does appear to be more frequent than "normally will not be noticeable".
