This is on a fresh EndeavourOS KDE install on X11, using Intel Xe Graphics. I haven’t changed animation speed or compositor settings. I’m unsure if this is a KDE or Endeavour issue.
Are you referring to the panel down the bottom? If so right click on the panel and enter edit mode click more options and change the transparency settings
I see it now, took me a while to spot it. I don’t seem to have the issue on mine, have you changed the animation speed at all?
Sorry just noticed that you said you didn’t
