A problem with Chromium after last update (bad rendered content)

Sat Jul 13, 2019 5:02 pm

Can you check if this page:

http://pogodynka.pl/polska/radary

displays correctly on RPi4 with lats Chromium update or it is my local problem?

On the square in the center of the screen there should be a map of Poland with rainfall data. There is a big mess there instead.

This site worked OK before and it works OK on my PC.

I don't know if it is my local program (messed up settings on my RPi) or there is the problem with the last update

It is working OK for me on my pi4 2GB with latest updates.

Have to agree with neilgl - headless Pi but works fine over VNC

Looks like rain headed your way :cry:

Happening here too on Buster desktop with all the latest updates.
I noticed this on some images don't show and whilst one's that do show, they're merge into one.

Maybe a bug?

The site works OK with old video driver. Switching to new=a mess. I tried to reset the browser to factory setting, no change. This is so far only one address which gave me such an effect... the address is important, it is main Polish weather service.

The RPi is 4 GB and this is the newest firmware by rpi-update. Also I did sudo apt-get update/upgrade

apt-get update gave me this comment:

E: Repository 'http://raspbian.raspberrypi.org/raspbian buster InRelease' changed its 'Suite' value from 'testing' to 'stable'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

???

Maybe someone have a hint how to start debugging this? Browser settings change, etc...

To clear the status change message just run

Code: Select all

sudo apt-get update --allow-releaseinfo-change
though I thought you should be prompted Y/N to the original question - answer Y would do the job.

This is due to Buster going live on the Pi before the formal release :)

Once that’s complete just run the update / upgrade again.

Different commands. They ran apt-get which won't prompt you. apt will.

The page you have linked appears fine in Firefox ESR to me ( lots of rain in poland right now ! ), but totally messed up in Chromium : it is all mixed like a jigsaw puzzle randomly assembled, and the rain layer isn't visible at all.
I did notice in firefox-ESR some images on some websites render like a game with a texture bug, or like some corrupt videos : lots of compression square or rectangle patterns, some shapes and contours that you can actually recognize, and globally totally messed up colors.
It really looks like something is wrong with image / video display / compression

This is with the raspberry pi4 with latest update / upgrade

Here is what http://pogodynka.pl/polska/radary looks like in firefox-ESR on the pi4 :

and in Chromium :

Works fine with me on a USB-SSD boot RPi3B+ Raspbian Stretch Desktop, in Chromium with 13 tabs active.

if this is some sort of map, it loads incredibly faster (no joke!) than google maps!

just checked it also on a USB-SSD boot RPi3B Raspbian Stretch Desktop, in Chromium with 15 tabs active.
loads quite good as well (peeked up to the intersection near Teodory, raining there probably).

on both RPi, just did a recent update 6 hours ago, prior to checking the liked site.

Ok might as well post how I saw it on the 15 active tab chromium on the RPi3B (sorry cant find Teodory anymore, but peeked into some sort of airport at Konopnica)

As far as I know they get these maps from OpenStreetMap https://www.openstreetmap.org

But then OpenStreetMap works with RPi4/chromium while this radar map doesn't work.

It works OK using Firefox on the same RPi so I have a workaround which allows me to not switch on a big PC to look at these rain maps.

On my RPi 4GB with up to date firmware and software, running Raspbian Buster :

Code: Select all

pi@pi4:~ $ uname -a
Linux pi4 4.19.57-v7l+ #1244 SMP Thu Jul 4 18:48:07 BST 2019 armv7l GNU/Linux

I can confirm the web page looks wrong for me too.

I confirm that this is still a problem even after apt update and rpi-update. That site above renders fine in Firefox-ESR but not in Chromium. I also get similar results from https://pskreporter.info/pskmap.html with map corruption in Chromium. Looks like I'll be using Firefox for a while until this is sorted out.

The current build (74.0.3729.157-rpt5) is completely broken. The "--headless" option also crashes every time time. You can wget binaries from https://launchpad.net/ubuntu/xenial/arm ... um-browser and then "sudo dpkg -i chromium-browser.pkg", but then the package manager will scream at you every time you use it. The xenial bins work fine in my experience and don't crash all the time like the current build. Using them for CI work under puppeteer and they work great.

I guess its good to hear that others have this same issue. These map display issues also occur with NOAA's forecast site: https://forecast.weather.gov/MapClick.p ... 0999999994

Edit: I also tried the latest build of Vivaldi for the raspberry pi, it also has the same map graphical corruption on NOAA's forecast site. I have a feeling this has nothing to do with the build of Chromium, but more of an issue with the graphics driver/kernel...

Could you try https://www.raspberrypi.org/forums/view ... 4#p1524254 ?

It looks okay to me, but I haven't checked that it wasn't okay before upgrading.

It looks like that did the trick. Maps on weather.gov seem to be fixed. Other sites posted in this thread seem to be fixed as well.
