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.

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
linux-generic (5.3.0-12.13) eoan; urgency=medium
* Master version: 5.3.0-12.13
I will provide xorg log too

I am running into the same issue.
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.

That's good to hear! Does anyone know whether the fix will be backported to the 5.3 kernel? It's gonna take a while before 5.4 becomes mainline.
