Created attachment 145372 [details] 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
I forgot to mention that I have been using oibaf's PPA in addition to the other software. I was under the impression that I had to do this for the display to function.
A workaround is to enable SWCursor in Xorg
Please attach your xorg log (if using X) and your dmesg output. If this is a regression, can you bisect?

I have attached the logs but do not know how to answer your question, this is my first bug report.
>> If this is a regression, can you bisect? > do not know how to answer your question, this is my first bug report. Regression: Was the bug always present (as far as you know) or did it work in the past? If it worked previously you can do a "git bisection" to find the problematic change. This increases the likelihood that AMD's driver developers can build a fix quickly.
Thanks for the explanation. I only recently bought the graphics card and the bug occurred the first time I used it on linux
I updated to the 5.3 release but has not fixed the issue
issue occurs with the closed source drivers too, on kernel 4.15 (linux mint 19.2) but to a much lesser extent
Issue is not present in Ubuntu 19.10 beta
Nearly nobody knows which versions are shipped by some distribution in some release. Please always provide version information - thanks.
running Xubuntu 19.10 - version information below (sorry for not providing it earlier): linux-firmware (1.182) eoan; urgency=medium * Rebase against git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git 6c6918ad8ae0dfb2cb591484eba525409980c16f linux-generic (5.3.0-12.13) eoan; urgency=medium * Master version: 5.3.0-12.13 xserver-xorg-video-amdgpu (19.0.1-1) xorg-server 2:1.20.5+git20190820-0ubuntu3 I will provide xorg log too

I am running into the same issue. Arch Kernel: 5.3.5 llvm: 9.0.0 Mesa: 19.2.0 xf86-video-amdgpu: 19.0.1 Linux-firmware: 20190923 Let me know if I can supply any additional information.
I ran into the same issue but after installing linux kernel 5.4rc2 it was fixed.

I do not believe it will get backported since most effort is going towards 5.4, but you can try a ditro like Manjaro that officially supports the RC kernels
