Playback Issue with VLC

[rdlf4]

Hello there, Kubuntu community!

Ever since I've installed and tried Kubuntu on my AMD-based laptop, I've seen some issues when playing videos with VLC.
The main issue here is how bad the image looks, whether a video file is being played or just paused.
I get these horizontal lines, low-res images and initially I thought this could be an isolated issue that could just disappear after updating the system. Nope, it's still there.
Tried an AppImage version from VLC website because both stock version for Kubuntu (3.0.9) and the Snap one show me the same visual disturbance/artifact. To my surprise, the AppImage did what other versions couldn't, and it's on v3.0.11.1. However, this morning I received a video-driver-related update and after updating, this issue now extends to the AppImage. Have a look:


Focus on the background. Images in the video have the "trilinear " effect. It's like that for both VLC 3.0.9 and 3.0.11-1 Vetinari (AppImage).
Because I was able to get around that issue with another software version, I think this could be related to Kubuntu in some way. Or is it entirely VLC's fault?

Have you ever had this issue before with VLC? If so, how did you manage to fix it?
Please let me know.
Thanks in advance.

I get a green stripe across the top of the picture with VLC. To fix this, I've started using SMplayer (GUI + Mplayer). No weird stripes, just better video.

Or, you could roll back to your previous video driver, the one that works, and lock it so that it doesn't update.

Hi nrdlf4
And, welcome to Kubuntu forums!

I am using KDE Neon latest user build and VLC, Kaffein and Mplayer all are working correctly.

Using Kubuntu 20.10 VLC is working properly, it is the only player on the OS.

I found the following on the net about anisotropic, bilinear and trilinear

https://gaming.stackexchange.com/que...-texture-filte

However, from your appended image which seems to be a "wrestling" event that had either a 'video wall" or "actual videos using a "zoom" type situation I do not see any of the three that are discussed in the appended link.

However, I do see three 'red lines" that seem to be the plastic encased wrestling ring ropes but I cannot see the particular situation of the "trillinear / bilinear, anisotropic" situation, such as in gaming:



so, possibly come back with some more information for folks who are much more knowledgable in this.
