Can you bisect?

 Try mesa git or 10.5.0-rc1 or up, or just patch older mesa... i am mostly
thinking of this patch:

http://cgit.freedesktop.org/mesa/mesa/commit/?id=a338dc01866ce50bf7555ee8dc08491c7f63b585

 Not sure if helps Minecraft exactly, so it is just a guess because i have
another games which stutter similar to what you describe before it.

Does it work better with the current Mesa Git 10.4 or master branch?

I just tried out mesa-git 10.6 (as that was available in the Arch AUR and I
wanted something quick to test) and the stuttering/frame drops still occur.
Although entering/exiting fullscreen on 10.6 don't seem to be as buggy as
before in Minecraft. I will try 10.3. and see

Uh I am not sure, it runs fine on 10.4 at acceptable framerates, sometimes a
bit over 100 but once chunks starts to load (more of the map loads) I get a
massive frame drop to 1 or 0 and then while it starts catching back up it just
stutters). I just tried 10.6-git from arch AUR and its acts pretty much the
same as 10.4

 The best is if you can bisect mesa, if 10.3 worked fine it should be easy :)
Or try various settings in game, might be only one which trigger slow case. 
Or if someone other want to reproduce it, apitrace trace will be usefull,
etc...

 Otherwise more info is needed, like:

 Which version of Minecraft?
 Java or openjdk used?
 Did you use optifine?

 You might post your options.txt file, because as i said it might only happen
with exact settings and also optionsof.txt in case you use optifine, etc...

Bisect mesa? I found this in the arch linux wiki
https://wiki.archlinux.org/index.php/Bisecting_Mesa so what is it really? Its
to notify the mesa developers from git? I am not sure lol sorry. I am going to
do some more testing, with Mesa 10.3 and Mesa 10.4 and different versions of
Minecraft. I am very new to the whole reporting bugs on linux and don't know of
these beautiful programs that exist.

The issue seems to no longer occur on Mesa 10.5.4, I am also on kernel 4.0 (I
dont remember if it did not occur on Mesa 10.5.4 with kernel 3.19)

I guess this is solved? I don't know what was done to solve it but the
stuttering no longer occurs and FPS has increased by 10-20FPS.
