It could be worse, it could be left hand side and not have start menu, though that is pretty common. Not seen this before.
Could try upgrading graphics though this seems more a windows thing.
you could try turning all notifications off, as that is where the alerts appear first
chose all settings/system/notifications and actions
turn off Get notifications from apps and other senders
scroll down to bottom of page and turn off all the apps listed.
I don't know if that will fix it, it was just an Idea
can try this, it might help:
right click start button
choose command prompt (admin)
type SFC /scannow and press enter
this scans system files and may fix this behaviour
