Text/Icons Missing after Unlocking Screen

On Ubuntu 20.04, I sometimes notice that after unlocking screen, text is missing from dialog boxes:

and icons missing from the task bar (left hand side, orange dots visible):

The clock and mini icons at the top of the screen are missing too.

Is there a way to get them back without restarting the system? I have numerous applications running and want to avoid having to save and restart them.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
