After I was updated to Linux 4.15.3 (and mesalib 18.0.0_rc4, but it works on Linux 4.14), I now get severe rendering issues making websites nearly impossible to use, and larger images are prevented from fully loading at all. This includes wallpaper before and after login. Disabling Intel IOMMU (intel_iommu=off) or switching to the previous kernel clears up the issue.
Here's a blurry, shaky video I took with my phone: https://www.youtube.com/watch?v=Nxe7oIc-Ie8

I have an AMD Radeon RX 580 that works in Windows. CPU is an Intel Core i5-4690K.

Here's my dmesg output after opening a larger image:
Here's the image in question, if that helps:
This issue does not occur on Linux 4.14.18-51, which I've just tested. Glad it was still installed.
