If the location and shape of the problem never changes then one possible explanation would be small areas of failing RAM on the graphics card.
It might also be a software bug of course. ** Summary changed: - Screen displays dynamic corruptions + [nvidia] Screen displays dynamic corruptions ** Tags added: nvidia ** Package changed: xorg (Ubuntu) => nvidia-graphics-drivers-340 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1834554 Title: [nvidia] Screen displays dynamic corruptions Status in nvidia-graphics-drivers-340 package in Ubuntu: New Bug description: Regularly the screen displays corruptions that change depending on disk i/o, keyboard/mouse and other system activity. The screen corruptions do not appear on each session and can be removed by selecting an alternative resolution and then changing back (or reverting without accepting the change). The location of the corruptions is stereotypical and always has the same shape characteristics.
