--- Comment #2 from Scott <shagooser...@gmail.com> --- In the last 3 days the issue has not reoccurred. Two programs it did effect were Firefox and Kate, both can require large amounts of scrolling. It appears that this issue may have resolved itself as a result of the work I did to get grub to display on boot. Ubuntu 22.04 is very fragile when it comes to the display setup. This also fixed up an issue where my USB printer was identified by the OS but subsequently could not be found by any other app. Fixing the display problems negated any need for a work around in my dual boot system to display the grub menu options or the UEFI boot screen. I realise this is not a KDE issue, and to a large extent beyond their control, but for Kubuntu to work properly with a (my) Nvidia GPU requires 2 monitors when using modern hardware is a problem. Kubuntu will not boot correctly unless a monitor with a DVI input is connected, requiring in my case a 2 monitor setup. The real issue is the GPU output port rather tshag2020han the monitor input. I understand the root cause is because the Nvidia GPU does not initialise the Display port until after grub processing is finished. It appears that if the grub menu is not displayed on boot then these other hardware issue pop up, eg printer and mouse which is somehow connected to X11. There is a whole bunch of other issues connected as well, for example, if the display setup is not absolutely correctly my 2K monitor is setup with a maximum refresh rate of 60Hz (it should operate at 144Hz) causing screen flicker and the refresh rate cannot be changed (varies according to the physical connection to the monitor). -- You are receiving this mail because: You are watching all bug changes.
