The most recent example of this is a 10 move loss by GM Qun Ma to IM Danny Reznikov in the Groningen tournament. Failing to analyse all checks and captures, Ma missed a queen sacrifice that left Reznikov ahead material. While Ma could have played on, albeit with a big disadvantage, he decided to end the game at that point. For Ma this is probably just one game in what will be a long career, but the nature of the loss (and blog posts like this) may make it hurt for at least a little while.
