Last couple of days with no upgrading done for over a week unwanted issues have come up.1) extended text in all apps such as texts editors and browsers will scroll to the end of the line. no matter what I do to get it back to the beginning it scrolls back to the end. Using mouse, home key, arrow key nothing helps.2) ctrl key alone always shrinks font size in all apps. Example: ctrl+s will save page, but until I hit the s the font will start shrinking quickly. ctrl+0 does fix things.If it was M$ I would think a virus. As I am using almost up todate buster not so much.Options I can think of:A corrupted/changed file that is executing commands that is causing this behavior.kernal corrupted and needs a fresh start.Hardware breaking down and need a new computer.What can I do to test which option is the problem? Or could it be something else I have not thought of?
Note: tried e4defrag and did not fix issue have not done fsck yet.
