video of the cursors motion when moving the mouse at a reasonable speed

Overview: After updating kernel to 5.3rc + firmware from
https://people.freedesktop.org/~agd5f/radeon_ucode/navi10/ I am experiencing a
very laggy and erratic cursor when using a Radeon 5700 XT

Steps to Reproduce: Use a navi10 card with the latest kernel and firmware.
Tried many desktop environments with both Xorg and Wayland

Build Date & Hardware: Built September 2019. AMD Radeon 5700 XT


Additional Builds and Platforms: Issue doesn't occur if I use a Radeon RX 580
instead of the navi card and isn't triggered on Windows 7/10
