I Had this problem since I bought the card, I reported it with every driver update and it's still not solved
When moving the mouse the screen stutter. It happens only in desktop use not while gaming.
ryzen 3700x stock
crucial 3000mhz 2x8gb
MSI b450-A PRO (AGESA 184.108.40.206 B)
card: 11293-01-20G (SAPPHIRE PULSE Radeon RX 5700 XT 100416P8GL)
steps to reproduce:
-set refresh rate to 100hz on 3440x1440 (ED347CKR monitor) on display port
-be on windows 10 desktop or any desktop application
-move the mouse in circles for few seconds
-a massive single stutter will happen randomly every ~10-30 seconds
-the stutter will be very noticeable on the moues cursor
-If you happen to have a program open (ex. youtube on chrome) the stutter will also be visible on the video
Other VERY IMPORTANT features of the bug:
-It's on every driver I tried since I bought my 5700xt back in November/October
-Only happens at 100Hz but 60Hz doesn't have the problem
-Disabling the graphics card in device manager will prevent the stutter (confirming driver issue)
-It happens on my Acer ED347CKR monitor, but I have no other 100hz monitor to test on
-Happens regardless if FreeSync enabled or disabled
-NEVER happend on my old HD 7970 Ghz edition on the same monitor
-NEVER happens in-game, only in desktop use
-Also happens in linux live usb (ubuntu 20.04), also alleviated by 60hz in linux.
-On HDMI (with freesync on) it happens much less frequently but the stutter last longer/cursor freeze for a bit longer.
