Hi,
That colored icon should normally only appear when the taskbar search is open. In this case, it looks like an icon rendering glitch occurring after the device wakes from sleep. When was the last time you rebooted your laptop? A restart often helps refresh the system and clear out these temporary display issues.
If the problem persists even after a restart, try updating your graphics driver or checking for the latest Windows updates, as these can also address rendering glitches.
