Well:

Fixed Issues

  • With v-sync enabled FPS may be locked to 30 on some displays set to 75hz refresh rates.
  • System instability may be experienced on some Radeon RX 5700 series graphics system configurations when watching video content in a web browser.
  • Audio for clips captured by Radeon ReLive may be corrupted or garbled when desktop recording is enabled.
  • Radeon Settings may list core clocks as not available with some Radeon RX 5700 series graphics system configurations.
  • Enabling Enhanced Sync may cause game, application or system crashes on Radeon RX 5700 series graphics products.

Maybe your card is really defective.

Time to try a RMA.

This driver update fixed a lot of problems I've been experiencing. The only ones that remain are the horizontal flickering lines and the monitor repeatedly losing signal while in the motherboard bios. I have yet to see @amdmatt  say anything about that particular issue. I believe its bios related and it will take some convincing to get any vendor to update the bios to fix it.

19.9.2 did fix the VSync issue for me...

But it completely broke VSR (or GPU scaling). Image is not scaled, no matter the scaling mode I use (or disable scaling). Toggling VSR and GPU Scaling also resets the desktop refresh rate to 60Hz. I am using a 2560x1080 display, 150% VSR works but the image is not scaled.

As crayraven stated, it did not fix flickering lines, but it is expected as it is listed as a 'known issue' and not a fix. No BSODs or other issues yet.

were those flickering line in reference to freesync? If so it didn't fix it for me either. And while my vsync works it seems to have a lot more input lag than I remember vsync having. Although whats nice it this update for some reason lets me play the witcher 3 while the last didn't. Sadly I've had a new problem where the screen will for whatever reason change colors. This first happened when I clean installed the drivers and my screen became a super bright green, but when I restarted the issue was gone. I thought it was a 1 time fluke but a few minutes ago I tabbed out of minecraft and half of my screen was darker than the other. If anyone else is having this problem let me know so I know I'm not alone lol. Looks like they're making progress but still have a long way to go

At first I thought the horizontal lines were related to freesync, I think many people did. But now I do not believe so, I say this because I can disable freesync on my monitor and still get them. I'm not a tech engineer or anything, but if I had to guess it would be the black lines are related to the monitor signal.

My english is not good ill try my best to give some usefull info.

Like i said 19.9.2 didnt fixed my 75z problem, problem was when i set monitor refresh rate to 75hz wattman or any other software (Msi afterburner, trixx,hwinfo etc etc) show zero info about gpu (temps,vcore, clock speed etc etc) also if i play games when monitor is on 75hz card is not increasing fan speed (i almost burned my card) so basically 75 hz is unusable.

After the latest driver i decided to try some new things, first i noticed that problem only occurs on 2560x1440 @75hz.  Which means 2560x1440 60HZ or 1920x1200 75 hz dont have any problem, then i download a software called CRU (custom resolution utility) tried somethings like setting res to native lcd-standart lcd etc etc didnt helped.  Then i decided to manually change things, somehow editing pixel clock to 296.20 mhz (stock value 296.00mhz) fixed my problem now i can use 1440p 75hz resolution without any problem. Btw making it 300 mhz (76hz) also works, no idea whats going on or how its fixed my problem.

This fix made my idle temps 45C to 57C so im back to 60hz.

 My friend reported same problem, he is using rx 5700 pulse with AOC Q3279vwfd8.. So its definately not fixed for some people. Dont get it wrong, problem is not vsync,freesync, horizontal lines etc etc problem is 1440p 75hz is completely broken.
