wierd screen or web page issue in firefox [SOLVED]
« on: January 12, 2017, 12:04:54 pm »
hi,
I am starting to notice some kind of weird screen issue when browsing in firefox.
I go to distrowatch.com, it loads the page. so far good. but when I scroll, I notice some thing different. some kind of screen refresh issue.
something along the lines of screen tearing. I do not mean video rendering issue. have not tried that yet.

what I see is only during scrolling of web page. it is like not a smooth screen flow when I scroll. if carefully look at the text when you scroll you will see a distinct lag and kind of redrawing on screen.

hope my video card is not failing. issue happens only in peppermint. not in windows 10. not during run of PM 7 on VM. Only in Hard drive install I find issue.
Just how to check if my Video cards are all healthy and proper drivers are installed?
why this scrolling issue is occurring?

thanks,
harish p

Open Firefox and type "about:preferences#advanced" in the url bar and hit enter. On the "General" tab, uncheck "Use hardware acceleration when available" and restart the browser.

Does that change anything about the "weird" scrolling?

hi,
if i enable smooth scrolling in preferences->advanced, i get that effect of weird scrolling.
after disable it is good.
But what i do not understand is the effect of smooth scrolling is not like smooth or pleasing. is it working the intended way?
i have created a video and you can see the effect i am talking about. is it how it is supposed to look or behave?

url: taking time to upload. will post it shortly.
thanks,
harish p

Yeah, the smooth scrolling is definitely NOT working as it should be! I would just uncheck it since you have pretty good scrolling without it...
BTW: Nice video!

Can't see anything wrong in your inxi...

Do you have screen tearing when watching this video?
Code: [Select]
https://www.youtube.com/watch?v=5xkNy9gfKOg
Moving your mouse over the video while it plays should invoke screen tearing if there's any.
It's normal to see some "blur" but the black bars shouldn't break horizontally.

Did you try another browser to check if it displays the same issue?

I see you are using an "Intel Broadwell-U Integrated Graphics" card...

Try this: FIX SCREEN TEARING ON INTEL GRAPHICS CHIPS
Follow it step by step and please report back if the screen tearing is gone or not!

hi,
the issue is solved. but this question is for understanding root cause only.

I am using peppermint 7 for close to 5 months in the laptop. this problem did not arise in the past. only in recent 1 month I see the problem.
I do not know why suddenly it came up? does any kernel update/fire fox update/flash plugin update can cause issue?

thanks,
harish p

Hi harishpathangay,

A simple answer is yes.  Peppermint is at the mercy of software developers and graphics card developers and the Linux Kernel.
At any time a regression can occur which may effect your hardware / software - that is the nature of the beast.
We are fortunate to be part of a very active / knowledgeable community that can help / assist / diagnose and hopefully fix these occurrences.

Hi,
Very True Indeed.
Also I see a lot of Linux distribution from Isles of Man.
Any specific reason for this?  Is there any broader initiative behind that? just curious.

Thanks,

Haven't heard of any but Canonical(company behind Ubuntu) and it's multi-DE offspring: Xubuntu, Lubuntu, Kubuntu(although I heard Kubuntu broke up with Canonical, but Distrowatch information is often outdated), Ubuntu Gnome, Ubuntu Kylin, Ubuntu Bugie being from the Isle of Man. Long story short, it's a tax heaven, and Mark Shuttleworth decided to register his company there.
Actually, most British Oversea Territories are tax heavens. Including Ireland ;)(ok, it's not actually a BOT, but it is a tax heaven)
