I'm having issues with graphics on my system. The operating system seems to run
fine, but while running applications like Blender, Godot and Inkscape, there is
a noticeable lag between moving the mouse and the content in the viewport
moving. In Windows, it feels instantaneous. I’m also having poor graphics
performance with running Windows VSTs like Xfer Serum inside of LinVst and Wine.
I've tried installing both the stable and unstable drivers from the Padoka PPA.
I've also tried many different distros like Manjaro, Linux Mint, Ubuntu, Ubuntu
Studio, and Fedora, but it still behaves the same.
I discovered that unchecking "Enable display compositing" in the XFCE Window
Manager Tweaks settings seems to make Blender feel more responsive. But then
everything has screen tearing, and it still doesn't feel quite as responsive as
it does in Windows. I've tried installing the compton display manager, but it
still behaved the same.
Using the proprietary amdgpu-pro graphics drivers with Ubuntu Studio 18.04 did
seem to fix the issue with Blender, Inkscape, and Godot. But it doesn’t fix the
issue with LinVst, and I get worse performance in games. Also, I would prefer
to use Manjaro.
My system is running an Intel Core i7-4790k cpu, 8GB DDR3 ram, ASUS AMD R9 285
graphics card, and an ASUS Z97-A motherboard. Also, the USB devices I'm using
is a Cooler Master keyboard, a Razer Deathadder mouse (the original one), an
Audient iD14 audio interface, and an Alesis Midi keyboard. (I did try
unplugging those and using a generic Logitech mouse and keyboard, but that
didn’t help.)
These are some logs using Ubuntu Studio 18.04 and the default graphics drivers:

I also first posted my problem on linuxquestions.org if you want to see the
things I’ve tried already:
