Kde animations stutter after new GPU
I am running Manjaro KDE and just put a new RX 5700xt in my computer and fresh installed Linux. The animations for windows (closing, opening and moving etc) and my mouse movement all seem to stutter every so often (about 5~8 secs), I am not sure what to do, the GPU runs perfectly fine on my Windows installation.

First thing I would try is changing the compositor backend in KDE display settings, as that is the most common cause of KWIN stuttering for most people.
Barring that, you should know that there are multiple different drivers for AMD cards in Linux. For the 5700xt, a newer card, you can choose between
amdgpuandamdgpu-pro. The former being open-source and the latter being the driver provided directly from AMD. The open-source driver is quite good (and comes installed by deafult) but for newer cards it might lag behind theamdgpu-prosupport on linux, so you might want to consider installing the proprietary driver from AMD if nothing else helps. The proprietary one usually has slightly higher performance, too.I will try what you suggested and get back to you thanks for the advice
Happy to help!
I tried changing the compositor in the Kwin settings page, OpenGL 3.1,2.1 and also XRender none of which made a difference. I looked into amdgpu-pro but according to https://www.amd.com/en/support/kb/release-notes/rn-radpro-lin-16-40 its not compatible with Rx 5700 series. I guess at this point I will just have to wait until the card is supported
