Blue line in timeline error

[Khairul27376411z6au]

The blue line on my premiere pro timeline has a bug.

Since yesterday I have been using an external 2K monitor, but when I opened Premiere Pro there was something strange with a blue line on the timeline.

The dot seems more advanced than the blue line, so when I use the razor tool or cut clips it feels very strange and uncomfortable.

Can you guys help solve my problem? I am very grateful for your help.

This looks like a UI glitch.

Does it go away when you disconnect the external monitor? If not, try resetting your prefs:

You are very zoomed into your timeline. Try pressing the backslash key and see if the blue line disappears when you zoom out.

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site. If NVIDIA, do a clean installation of the 517.40 Studio Driver (NOT the Game Driver)

If that doesn't work, try creating a new project and import the old one into it.
