[Bug 1480568] [NEW] Screen tearing when scrolling in Chromium

2015-08-01 Thread Kaspar Tint
Public bug reported:

When Chromium is in maximized, very evident screen tearing is seen when
scrolling the page.

I recorded the problem on to a video which is located here:
https://www.dropbox.com/s/h7egaut8lbx9wzs/Screencast%202015-08-01%2017%3A54%3A48.mp4?dl=0

This should be downloaded because dropbox probably shows the video with
worse quality in it's web player.


Notes:
   * The tearing is evident when the window is maximized
   * As seen in the video, when moving the window to the right, the tearing 
will fade out from the Chromium window
   * This leaves me to belive that the tearing is caused by some other object 
that is maybe invisible on the desktop otherwise?


Info about the system:

   * Ubuntu 15.04 (64 bit)
   * CPU: Intel i5-3337U

I also attached the video on this page.

Here is a way to temporary fix the problem:

[Bug 1351950] [NEW] Ubuntu does not put CPU into idle state

2014-08-03 Thread Kaspar Tint
Public bug reported:

When booting into Windows partition, it manages to downclock and lower
the V-core of my Intel i5-4570 CPU. This gives me a steady 25 C
temperature during idle time. (measured with physical device and
measured with Windows application called SpeedFan).

On Ubuntu, this does not seem to happen. Even if I do echo ondemand | sudo 
tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor  , the CPU 
temperature is still about 40 C high during idle time. 
I do this measurement after clean boot, CPU usage is 0-6% and temp is 40 C 
steady. 
I use xsensors to look at my CPU temps and frequencies.

This means that Ubuntu does not effectively downclock and lower the
V-core of CPU when computer is in a idle state. I belive this is true to
any version of Ubuntu now as I can see the effect on my Laptops that are
using Ubuntu also. The battery life is much shorter than it is with
Windows running on them.

I have made my tests with a desktop computer using:

CPU: i5-4570
GPU: GTX 760
Mobo: Asus B85-Plus
OS: Ubuntu 14.04 64 bit

Also made tests on various Lenovo thinkpads and Ultrabooks. Results
remain the same, Ubuntu makes the CPU a lot hotter because of the
reasons I posted.

[Bug 1310338] [NEW] wifi stops working

2014-04-20 Thread Kaspar Tint
Public bug reported:

Hi!

So I have TL-WN821N V4 USB wifi device. It connects to WIFI, I am able
to download and upload stuff via terminal for as long as I want to. The
problem occurs when I open up a browser (does not matter which one, have
tried all).

I open the browser and navigate to different pages. After like 5 minutes
of browsing, I am not able to browse anymore. Wifi is still connected
but no info is going though. I can also do a ping google.com in Terminal
and it will yield no result.

This bug occurs on my system that is running a fresh 14.04 Ubuntu 64
bit. It also occurred hwne I ran Ubuntu 13.10, and that is also the time
I ran the wireless script shown below.

Here is some info that I got with a script that is supposed to pur out a
lot of info about my wifi:
