Disabling the animation for opening windows can have unexpected side effects: If you remove the check mark at General > Windows > Animate opening windows with TinkerTool 6, renaming document files directly via the title bars of the corresponding windows won't work any longer.
Workaround: This is known defect in macOS. Apple introduced it with macOS 10.12 Sierra and it is still present in later operating system versions. To avoid the side effect, set the check mark at Animate opening windows again.
There are currently no known problems that require additional documentation.
