The glitch is still there.
Just after the computer restarted from installing GPU Tweak II, I turned off the log, unlocked it from the main window and closed it.
Switched to OC Mode.
Went into the settings for GPU Tweak to stop it the monitor from opening on every restart like I normally do.
Checked off apply settings each time GPU Tweak starts.
Went back to Home and minimized.
I noticed the graphical glitch it did before with the task bar, so I opened the Recycle Bin and the icons did the same thing where it takes a while to load.
Clicking things in Task Manager takes while to show up etc...
Ending the Desktop Window Manager from Task Manager fixes this when it restarts the process.
So weird that I cannot recreate the glitch the same way each time.
I used the latest removal tool too before installing.
Our software team recommend to try out this recently updated version of GPU Tweak (v188.8.131.52) it should have the updated DLL
