AMD late Monday released the latest version of Radeon Software Adrenalin 2019 Edition. Version 19.7.4 Beta fixes
a bug that caused "Grand Theft Auto V" to crash on machines with Radeon RX 5700-series graphics cards. The rest of its feature-set is identical to that of the 19.7.3 drivers. There's no mention in the change-log of the worsened idle fan-noise of RX 5700-series
graphics cards observed from the upgrade to 19.7.3. However I can confirm that the 19.7.4 drivers do not fix this issue.
