After I update latest version of libreoffice when I input Thai word in the bracket on Calc Application, it show shift position problem.
You better share a file. A screenshot only shows that you have a problem but is useful in finding the cause.
Thank you I added the sample file link yet.
However, when I see it on Google Drive, it show correct position.
Indeed, it looks fine in a browser window. However, there is no download option to see the very file. Just for the record: I have copied the contents of your file to a new spreadsheet in LibreOffice Calc 5.0.2.1, and it looks fine to me (although I don’t really know the Thai language and script). I tried to change the font, it is still fine. Thus, a usual suspect: you don’t have a proper font with Thai characters in your system.
Before update version (5.2.2) I can use it normally this problem just debut after update.
For me updating to 5.2.3.3 helped. (But I am on Win XP SP3)
Changing the OpenGL setting under Tools/Options/View might help you, but I recommend to update anyway.
