Hello, I am getting this bug too in my Ubuntu 24.04 LTS. This wasn't happening before I upgraded from 22.04 LTS. I noticed that there is a narrow 2-pixel high invisible horizontal bar somewhere on the screen that, when the mouse cursor is inside, causes the screen to flicker heavily. It doesn't matter, if there are any windows open underneath or not. So long as the cursor's Y location fits inside, the screen will flicker. I use 1920x1080 resolution on my laptop, and by using the "xdotool getmouselocation --shell" command I found out that the location of the bar is near the bottom of the screen at Y locations 890 and 891 (seems to change across reboots?).
Do you think this bug is related to the rest of complaints about flickering screens on 24.04 and Intel i915? I am getting some of these lines in the syslog: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2064017 Title: Xserver Display flickers when mouse pointer is inside narrow horizontal range band (kernel related) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2064017/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
