Stranger blue line in timeline

[xiangc0413]

The blue line didn't match the blue cube, which on the timeline. However, the frame I cut is all match to the middle of blue cube, only the blue line didn't. Even when the project play to the end, it still shows like it doesn't. All the projects match the middle red line I draw not the blue line software provided. It doesn't matter to use but it will confuse me some time. The only problem is how to make the blue line back to middle. Thank you for reading and hoping to know how to make it to middle.

Hi xiangc0413,

Looks like a redraw error. Can you update your GPU drivers and report back?

Thanks,
Kevin

Hi Kevin,

Thank you for ur help. However, I update my win10 system, but the problem still not solved. I don't really understand what is the meaning of UPDATING GPU. Would you mind tell me more details? Thank you.

Regards,

Xiang

Basically, head to the website for your GPU and download the most current drivers for your GPU model. Then install the drivers according to the manufacturer's instructions. Hope that helps.

Thanks,
Kevin

Hi Kevin,

I have the same bug. First, i had no problem with Premiere, but bug appeared after installing trial-version of Photoshop CC 2018

I have clean W10 system and updated GPU driver. Premiere Pro CC 2018 v12.1.2.

Do a clean install of the driver.

Leave all the fancy stuff unchecked.

I uninstalled driver and nvidia software (then tested premiere). installed and updated only "graphics driver" (then tested premiere)

And reinstalled Adobe Programs (encoder, premiere, creative cloud, codecs, etc)

but still bad working.

I have the exact same Problem and it is really annoying. Drivers are the latest available. Please FIX, ADOBE!!!

EDIT:

G-Sync (activated) Monitor with 144hz.

Yesterday I was forced to reinstall Windows 10, still same Problem.

[alexanderm34163910]

Looks like the Problem is caused by Custom Scaling in Windows 10. Premiere and other Adobe Software Products can't handle custom Scaling.

Solution:

Go to Settings --> System --> Display

Look for "Scale and Layout" - Set it to 100%, Restart eventually --> Problem solved

Yes 125% is known to give issues.
