weird browser-on-the-right side issue

[walter wu]

I have a DELL inspiron 14 5000 laptop. Dual boot with windows and Ubuntu. I have a large external curved monitor (32 inch DELL). Here is a weird issue:

If I position the browser on right half of the external monitor, it is not responsive. It is very slow even just to scroll up and down.

The interesting thing is 1) as soon as I move the browser over the middle line to the left side , the problem disappear. 2) it does not happen on my laptop screen.

I have not tried using other external monitors.

Any idea ?

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner.

You refer to a browser but which one? Firefox, Chromium or another?

You attempted to submit this report against 'evince' which is a document viewer used mainly to view PDFs. Does this issue also affect evince?

If you still see a problem related to the one that you reported this bug report needs filing against the correct package as per https://wiki.ubuntu.com/Bugs/FindRightPackage to ensure that the right developers are made aware of the problem.

Chrome and firefox. It is nothing to do with PDF.

Thanks. As two browsers are affected and presumably no other applications (or you would have said so) I'm unsure of which package to assign this issue to. Could be gnome-shell, mutter or maybe a package you have installed related to your hardware. Reassigning to mutter for now. I'm unsubscribing as the Desktop team will pick up this issue within the next day or so.

Thanks for the bug report. We need more information about the graphics on this machine so please run:

  journalctl -b0 > journal.txt
  xrandr --verbose > xrandr.txt
  lspci -kv > lspci.txt

and attach the resulting text files here.
