Bug description

Icons used for app shortcuts are circular irrespective of the icon style chosen in system settings.

Steps to reproduce

• Long press on the app icon to bring up app shortcuts

Actual result: Icons used for the app shortcuts are circular, embedded within the icon shape selected in system settings leading to empty space at the edges Expected result: Icons adapt to the shape picked in system settings

Screenshots

With the squircle shape selected, this is what things look like presently in Signal:

This is how Discord handles it:

Hi! Thanks for the bug report. This should be fixed as of 5.16 which'll be rolling out soon to a beta near you!

Due to how shortcuts work, this may not fix itself instantaneously. As a workaround once you are on 5.16, I'd follow these steps:

1. Enable screen lock in App Settings -> Privacy -> Screen Lock (this will delete all system shortcuts)
2. Close the signal app
3. In System app settings, clear cache for signal app (WARNING: Do not clear data. Only cache.) This will make sure Glide (the image manager library Signal uses) doesn't have any out-of-date shortcut bitmaps in it's file cache.
4. Open the signal app
5. Disable screen lock in App Settings -> Privacy -> Screen Lock (this will re-add all system shortcuts)

Clear cache might not be necessary, as I've also added a version number to the key that the cache system uses to locate the proper file, but it doesn't hurt.
