RX 4701x HDMI1x DVI-DMinor stuttering occurs while DVI-D monitor is off, does not occur if HDMI monitor is off.
Driver version: 18.10.2
Other threads on the forum showed that this issue was fixed, it was also on the release notes of an optional driver - 18.9.1, although after installing that specific driver, the issue remained.
Can experience the issue when running applications on windowed mode and borderless, games running in fullscreen aren't affected by the issue.
You're right. It should not be marked as fixed.
I'm no longer seeing the original you mention. But.. Here's another thread as this one might be closed.
