Sometimes I have strange artifacts (see screenshots) in Firefox with my RX580 under openSUSE Leap 42.3.
In other applications i can't see any type of them. Also under Windows 10 (Dual-Boot setup with GRUB) my RX580
works without these problems.The artifacts appears on dropdown lists in Firefox. Disabling Hardware Acceleration
in Firefox didn't fix this.
I don't know what i schould do. RMA? This RX580 is a replacment card already. Had a RX480 before with the same
OS: openSUSE Leap 42.3 (I know AMD doesn't support this OS.)
Card: Sapphire Nitro+ Radeon RX580 8GB Limited Edition
Driver: amdgpu-pro 17.40-492261 (and previous versions)
About the screenshots: Screenshots with the file ending *_normal.jpg are how it should look like.
