Hey everyone.
I'm running a 5.1 classic Mac Pro with an RX580 8GB Sapphire, OCLP 2.4.1, and MacOS Sequoia (the same problem was also present under Ventura).
I'm facing a problem after replacing my old HD 5770 with an RX 580.
It seems like any vector graphics in Chromium-based apps completely lack antialiasing and instead snap to the nearest pixel.
I've attached images showing what I mean - one, with smooth, antialiased graphics from the old HD 5770 with patched kexts and one from the 580.
The issues also go away once hardware acceleration is turned off in browser settings.
I've tried looking around on the OCLP GitHub, Discord server, and here on MacRumors to see if this has been mentioned anywhere, but I couldn't find anything. Sorry if this is a repost of an old issue. The legacy Metal support page on the OCLP GitHub doesn't seem to mention this either.
I'd love to hear if anyone else has experienced this and if there's any known fix aside from disabling GPU acceleration in affected apps and suffering through the bad performance.
Thanks
