[Solved] Screen not refreshing correctly on Macbook Pro Retina 2014

Hello !

I have a problem with the screen refreshing, sometimes it's not refreshing in "real time" or not refreshing at all.

When I try to resize the columns in qbittorrent it's not smooth, the screen is refreshing a few seconds later. I have the same problem when watching a streaming video (720p) on the website crunchyroll.com, if I put the video in "fullscreen", my screen stops from refreshing, it's like blocked on the first thing I saw when "fullscreening", I still can click to pause the video or quit the fullscreen mode, I also ear the sound, but the screen is not refreshing at all when it's in fullscreen mode.

I think it's a problem with my graphic driver, but I don't really know what is the problem or where to look for. Here is a lspci of my graphic card (integreted one) :

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Device 0a2e (rev 09)

Thanks for your help !

Have you installed the intel and mesa packages? The intel provides 2d acceleration and mesa provides open Which web browser are you using? What desktop environment are you using?
I recommend you make sure you're not missing the packages you need. They contain the drivers you need.
This ArchWiki link will provide you with everything you need to know.
Cheers! Let me know if this helps, or you need some further help!

I also found this link to be very useful. My Macbook is a different model, so not everything appiled to me, but it may help you!

Yes I have! Here's some output:

pacman -Qs xf86-video-intel
local/xf86-video-intel 1:2.99.917+381+g5772556-1 (xorg-drivers xorg)
    X.org Intel i810/i830/i915/945G/G965+ video drivers

pacman -Qs mesa
local/libtxc_dxtn 1.0.1-6
    S3 Texture Compression (S3TC) library for Mesa
local/mesa 10.6.4-1
    an open-source implementation of the OpenGL specification
local/mesa-libgl 10.6.4-1
    Mesa 3-D graphics library

cat /etc/modprobe.d/i915.conf
options i915 enable_rc6=1 enable_fbc=1 lvds_downclock=1

I'm using Firefox, and I'm using DWM. I've installed Google Chrome, and in Google Chrome it's refreshing... In smplayer if a play a video it's refreshing in "real-time", but when I click on the menu, it takes a few seconds before showing the menu. I don't know if I'm really clear? It's like the screen is refreshing slowly.

It's like some software have problems and others don't, hard to understand the logic of that for now, thanks for your reply!

Edit: I've found the problem, I misunderstood the meaning of tearing in the wiki so I though it wasn't the problem, but I checked the meaning of "tearing computer" on a search engine and it matched the description of my problem. So I just had to set the TearFree option to true, sorry for the disturbing!

The problem wasn't completely fixed, if the computer goes to sleep, the problem is reappearing after waking from sleep...
So I removed the TearFree option and I tried to change the acceleration method to UXA instead of SNA, it worked and after waking from sleep it's still working!

Edit: There was another problem after using UXA... The video decoding was very slow and unwatchable on smplayer with xv, so I tried to use vaapi instead of xv and it worked. I had to install mplayer-aapi but it wasn't building on AUR, so I tried mpv (a fork of mplayer with vaapi support), and I just had to configure smplayer to use mpv and vaapi.
