You have been subscribed to a public bug: The screen constantly lags and need several seconds to update the output on my device and sometimes causes horizontal stripes every time I boot from normal mode. It keeps lagging even when I press Ctrl+Alt+Fn and enter terminal mode. However, mouse and keyboard input still works as normal.
The problem first appeared after I resolved a package dependency issue on Feb 17 (but I cannot remember what package was causing the dependency issue) and then rebooted the system. But the problem disappears if I choose to boot from recovery mode (this is how I gathered information for my device).
