This is an intermittent issue. I’ve gone months without it present at all, and months with it present.
The lag affects everything except audio. Input and all visuals are frozen for the duration of the lag/stutter, including games, video, etc. It is very difficult to move the mouse around accurately during, because it doesn’t catch up to expected location, it actually stops receiving input.
Most cpu usage is task manager and ShareX (recording gif 24fps); openshell is not at fault either, just demonstrating menus with it.
Honestly it feels worse than it looks, 24fps gif makes it look less bad.
Restarting pc solves it temporarily when it rears it’s ugly face, but only temporarily. I’ve been trying to pin down the cause of this for years, searching every corner of the internet for solutions, but nothing seems to definitively exterminate the problem. It has persisted through total hardware replacements over the years. I have also run into this in previous windows installs (various versions), and multiple different driver versions (AMD). The issue appears and disappears independently of driver or other installations.
It seems to happen after something crashes, perhaps graphics related, which lead me to think maybe it’s video memory issues? Ctrl+Shift+Win+B has no effect, manually disabling and reenabling the GPU driver device has no effect. Restarting DWM has no effect. There is no detected DPC Latency. No discernible programs are affecting it. I have most non-essentials in windows disabled: no cortana, no telemetry, no updates, no unwanted indexing.
Speaking of windows updates; this doesn’t come from updates, because my pc never updates unless i tell it to, i’m very scorched earth with update policy. The issue has come and gone without any changes to OS.
All of that said, what could possibly be the issue? I’ve run out of troubleshooting steps.
