Screen Blanking for a second while playing video

Sat May 23, 2020 3:37 am

Hello, I am using a Raspberry Pi 4 2GB with a monitor of 1366x768 resolution. Monitor is connected via HDMI to VGA adapter.
1 month ago everything was fine. But now while I am playing video in mpv or omxplayer , the screen goes completely blank for a second.
This occurs everytime at some particulars positions of the videos.
The videos are not corrupted because I played them many times 1 month ago, and they played fine.
It is not a power problem , because my power adapter is very good, and i have never seen low power icon while using that adapter.

Am I the only one who is encountering this problem?
Is this the problem of my new HDMI to VGA adapter, or a GL driver bug or something else?

what about with vlc?
like chromium, vlc has been tweaked for the rpi.

Are the problematic videos local files or internet streams? I have in the last month occasionally experienced weird problems with some internet videos but never local video files. I have cable internet and usually get around 90-100mb /second but occasionally after experiencing problems with internet high def video I checked my internet download speed and found it had temporarily dropped to 10mb/s i suspect because of heavy internet use in my neighbourhood.

All videos are local files.
