Old Electron version in macOS client causes GPU system lag and crashes in Tahoe (macOS 26)

[nanoamp]

Describe the bug It appears that the Electron version packaged in the macOS desktop client triggers a widely reported issue with https://github.com/electron/electron/issues/48311. This results in system lag and WindowServer crashes that throw users out of their desktop session.

To Reproduce shared/package.json suggests keybase should be using 38.2.2. Using ripgrep, the version in the current packaged macOS download from keybase.io (v6.5.4-20250917154415+52400b6f28) reports as 28.3.1, and includes the affected call:

f=/Applications/Keybase.app/Contents/Frameworks/Electron\ Framework.framework/Versions/A/Electron\ Framework
app=${f#/Applications/}; app=${app%%/Contents/*}

# Get Electron version
ev=$(rg -a -m1 -o -r '$1' 'Chrome/.*Electron/([0-9]+(\.[0-9]+){1,3})' -- "$f")
[ -z "$ev" ] && ev=$(rg -a -m1 -o -r '$1' 'Electron/([0-9]+(\.[0-9]+){1,3})' -- "$f")

# Ripgrep the binary for affected _cornerMask call (https://github.com/electron/electron/pull/48376)
if rg -a -q -F "_cornerMask" -- "$f"; then
  echo -e "\033[31m❌ $app \033[2m(Electron ${ev:-})\033[0m"
else
  echo -e "\033[32m✅ $app \033[2m(Electron ${ev:-})\033[0m"
fi

Expected behavior The packaged Electron version should be one of:

• 36.9.2
• 37.6.0
• 38.2.0
• anything above 39
