--- Comment #41 from Pascal d'Hermilly <pas...@dhermilly.dk> --- @michael Just to be clear. it's not enough just to hover on and off over the close icon - you have to trigger window enlarge/shrink effect(mouse hover in/out of window) to get the lag. I didn't mess with the themes: it's Breeze on Intel graphics. Enabling the FPS desktop effect shows me a drop from 60FPS to 1FPS during the lag. -- You are receiving this mail because: You are watching all bug changes.
