It's not strictly only hi-DPI machines - that's just the most common place it is experienced. --- https://errors.ubuntu.com/problem/82f7f7e7923663c7b2123c7f1f49af29f6ff4d77 https://errors.ubuntu.com/problem/735a2b847e0eeab6c8a7b954de5110e43889be15 https://errors.ubuntu.com/problem/dcd4c9da5ee0cc6d36324446e0e49d39705c90b7 https://errors.ubuntu.com/problem/cb82f70f9ede07369e8104da9ddf87e28b42257d https://errors.ubuntu.com/problem/84a5563af3d2b85f098da832ece4cb8450bfd524 --- WORKAROUND: 1.
