Here are what I did: 1. Set the panel to auto-hide. 2. Remove all the widgets from my panel by deleting the config file, then I logged in. 3. After login, btop still reported near 100% gpu usage, but, when I moved the cursor to let the panel load the first time, the usage went back to normal. 4. However, after adding some widgets that dynamically updates(like timer,system monitor,etc), the fix in step 3 cannot fix it anymore. 5. I also tested a panel with a timer widget not counting down, in which case the fix in step 3 worked. It only became meaningless when the timer widget is counting. -- You are receiving this mail because: You are watching all bug changes.
