As many other people here, I still get crashes with RX 5700 XT on the newest version (19.7.2). It's better than 19.7.1 where I couldn't start even CS:GO but it still has very severe issues.
For example, if I start Apex Legends, only after 1-4 seconds in the main menu, it crashes the entire system and causes reboot. The same occurs if I try to go to the options menu in Rainbow Six Siege. Also UserBenchmarks have stopped working for me, even though I could run them immediately after install. Now either its 1st or 3rd GPU test causes a system reboot.
I've tried to completely uninstall the driver with DDU, revert to 19.7.1, uninstall it, install 19.7.2 again, reinstall Windows, switch to PCIe3, set undervoltage, disable FreeSync and GPU scaling. When I remove RX 5700 XT and install my old GPU (GTX 960) everything works.
I hope this issue gets resolved as soon as possible because I have to fall back to my old GPU for now unless I want to crash my system every now and then.
My specifications: MSI Radeon RX 5700 XT / MSI x570 Gaming Plus / 2x Corsair 8 Gb 3600 MHz / Corsair CX600 PSU
