Hi @Jeroen Bakker (jbakker) this problem still here.
as in picture,left was problem, right are close multithread scuplt in option ,
1,creat cube
2,in edit mode,subdived several times
3,switch to sculpt mode
4,create brush texture
5,switch to texture node editor, checked use node
6,back to sculpt mode, checked dynatopo on, set pix to 2
7,draw on mesh
the problem appeared use today master git branch

I compiled a new Blender on mac ,seems cycles works for me. either view shading mode or F12.

https://developer.blender.org/T65833 I've creat a bug report to solve the flaw block @zdy (NGENNGT) will handle this.

This problem is not limited to Dyntopo, any mesh with high enough density will show some defects. The problem seems to originate from node texture. I was able to somewhat isolate this particular problem.
I just picked a random lock to test things, the use of LOCK_NODES should not be relevant.

This submitted patch has been sent out directly by deleting the fuzzy translate items in many places.
The translation of an interface is not one man works.

windows 10 has a future is auto re-install GPU driver but not mentioned.
You can download a driver from nvidia's home page, then re-install GPU driver again manually.
This could solve a lot of situation when run blender on windows 10.

Thanks ,it works fine after git pull. waiting for 2.8 shipping time!

seems fine to me

I also encounter this crash.
System Information
win8.1 64bit | k2100M

@Aaron Carlisle (Blendify) thanks , yes It's spend four of us and one months to translate and reviews.

when I use this file in windows 8.1 python3.4

>python report_translation_progress.py ..\manual\locale\zh_CN\LC_MESSAGES

it always report :

@Tamito Kajiyama (kjym3) Thanks for the reviews and the explanation.
This patch is a copy and minior modify from D765, I'm not familiar with windows's IME mechanism. But we all glad see these kinds of CJK support .
I'll pay more time to investigate these code and do support the composite mechanism for every IME editor. Maybe the code already exist in master are a good start.
Thanks

Hi, I've started the chinese translate process for four or five months.
The work flow is : sphinx-build -b gettext produce pot then sphinx-intl update produce po file, then distrubute po file for someone translate then collection them to build html . I'v enconter so many problem and solved,especially the old sphinx-intl can't distinguish changed url item give me a new item in po, but the new one change the exist item and mark then as fuzzy item. this can reduce my work load.
Question is could I upload po files to repository and how. then can automatic build htmls.
I use sphinx-build -b html -D language="zh_CN" to build html.
thanks.

With some tests, there still exists some bug for chinese IME not on the D765 support list. like first character unexpect with latin ones in windows 8.1.
So ,I think there still some work to do with the IME though no crucial bug appears. Will do more tests in blendercn.Later.

@Julian Eisel (Severin) yes，will update the table when we call for test building , thanks!

quick test fix2.diff in win8 microsoft bing chinese IME,the double input no longer apear, and yes the double input are exit in bing chinese IME before.
thanks @Dun Liang (randon).
but I don't test korea ones, hope someone give these feedback, thanks!

Confirm this issue， windows 8 64bit ,and many chinese IMEs all fails, when not do confirm charactor input into the form and mouse click other place，Blender will crash，this problem was too unusual to find out.

this situation also confuse us from china traslaters. I was point out this question in second paragraph in this letter: http://lists.blender.org/pipermail/bf-committers/2014-December/044676.html
maybe Blender need a better gettext solution, make the string with the path ,then translater will know how to do with these same english words.

Hi

The last commit to master didn't include two file: GHOST_ImeWin32.h and GHOST_ImeWin32.cpp.  When I use Cmake,it tells me some file miss. Is this right? or should I do something. Thanks.

ps, when I copy two file above, and compiled. we test the building, And It work fine. If something we should take care to test more, let us know, thanks.

Can this table ok? I copy from Leon's sheet: Feedback - Asian IME Support in Blender

@Campbell Barton (campbellbarton)
I can confirm that chrome code not intruduce these limitations.
Because when we use chrome programme all IME can perfect input character.
If you need more evidence,please tell me the method how to get these thing to provide.

I've compiled the latest code form severin and distribute the 64bit binary blender to user and almost 50 users give the feedback. users from blendercn.org. I record these feedback in chinese http://www.blendercn.org/963.html.
Let me explain feedback record above：
There are two main windows platform when user use blender : windows 7 and windows 8
There are so many solutions for chinese version IME: PINYIN , WUBI ,SHUANGPIN, voice distinguish, handwriting distinguish etc.
There are so many companies develop IME: google bing sougou baidu etc.

We're very appreciate you can give a hands to help and change these codes to conforms the Blender fundation's architecture request and code style,

It's very clear that we who use chinese windows system need this patch, and linux users already have the IME support in blender.
Why this patch is very import important for us who use non-lantin system user, because we have the pain point on Windows IME support.
we deploy the Blender in our work, and we can't name the object and project in our owe language via IME. if we choose blender in team work, it's means we must face a fact that there are not every one are familiar with english,most of them don't know the means which write in english. and if we use another system like PINYIN to name our blend file , the PINYIN system mostly like an one---many index thing. eg: I name a object use chezhou in PINYIN , via IME will be 车轴 掣肘 etc. the different meanings of the PINYIN will make many trouble and reduce productive, this is why some team works can't deploy blender in work in china. so we crowdfund and find randon did this patch, and we not rich, couldn't afford more energy in much big thing now.

Hi, @Campbell Barton (campbellbarton) I think this patch https://developer.blender.org/T30274 already solve this problem in Linux. and we can use chinese input method in ubuntu. many users have reported they can input no-latin charactor on Linux platform.

IME support for X11 already implemented, for ubuntu user who use ibus could input east asian charactors in blender. @Campbell Barton (campbellbarton)
