From https://forums.macrumors.com/threads/found-a-solution-for-the-macos-mousecursor-hover-focusloss-contextmenu-bug.2450307/post-34609144

The culprit was Apple's iPhone Mirroring app.

The app was running background hooks at the system input level that were corrupting hover state. The tell was seeing it flicker in the menu bar.

Fix:
1. Open the iPhone Mirroring app on your mac and revoke access to your iPhone
2. Go to System Settings > AirDrop & Continuity > iPhone Mirroring and turn off iPhone Widgets
3. Go to Notifications & Live Activities and confirm "Allow notifications from iPhone" and "Allow Live Activities from iPhone" are both off

First, enable NSColorSimulateHardwareAccent

defaults write -g NSColorSimulateHardwareAccent -bool YES

Then choose a color with NSColorSimulatedHardwareEnclosureNumber with a value between 3 and 8 inclusive.

defaults write -g NSColorSimulatedHardwareEnclosureNumber -int 4

• 3: yellow
• 4: green

git log -Sword
git log -Gword

• -G by default accepts a regex, while -S accepts a string, but it can be modified to accept regexes using the --pickaxe-regex.
• -S finds commits where the number of occurrences of "word" changed, while -G finds commits where "word" appears in the diff.
• This means that -S<regex> --pickaxe-regex and -G<regex> do not do exactly the same thing.
