# This script is intended to temporarily bypass the "blank screen" bug in Anki on unsupported(?)
# GPUs (Dec 2021): <https://forums.ankiweb.net/t/anki-opens-but-all-windows-are-blank/8920/16>
#
# Adapted from a similar script by @ahihi for an app called "SuperCollider" that also uses qt on
# macOS: <https://github.com/supercollider/supercollider/issues/4136#issuecomment-605447703>

if [ -z "$APP" ]; then

    exit 1

chmod a+x "$SCRIPT"

INFO_PLIST="$APP/Contents/Info.plist"

echo "setting CFBundleExecutable = $SCRIPT_NAME in $INFO_PLIST"

defaults write "$INFO_PLIST" CFBundleExecutable "$SCRIPT_NAME"

# `defaults write` saves a binary plist, convert back to xml
plutil -convert xml1 "$INFO_PLIST"

echo 'done'
echo 'rebuilding the LaunchServices database may be needed'

/Applications/Anki.app/Contents/MacOS/anki-disable-gpu show error:
env: /Applications/Anki.app/Contents/MacOS/anki: Permission denied

so I change exec env QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu" "$DIR/anki" to exec env QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu" "$DIR/AnkiMac"
It runs
