In QGIS 2.18.14 Processing Toolbox I started to use v.buffer.distance to create fixed-distance buffers around my lines.

I can also make the buffer with square caps (straight ends).

However, I cannot make it without end cap. I mean, the option "Do not make caps at the ends of polylines" does not seem to work.

This is similar to this recent question v.buffer.distance does not create straight buffers in QGIS, but my situation is different, as I can make square caps (-s) while not being able to cut caps (-c). (Probably @Annekeds is using QGIS - GRASS plugin, while I am working through Processing Toolbox).

Strangely I can make buffer without caps when I run v.buffer.column... so my workaround for now is to use v.buffer.column with same distance in the field.

Actually, I cannot produce the same issue using both QGIS 2.14.20 and 2.18.14 whether I used v.buffer.distance or v.buffer.column, I got the same result when I Check both "Make Outside Corner Straight" and "Do not make caps at the ends of polylines"

Here is the result using QGIS 2.14.20:

Here is the result using QGIS 2.18.14

    Thanks @ahmadhanb! Lightning-fast. Umm...installing 2.14.20 for this does not sound much appealing... – Kazuhito Dec 6 '17 at 4:54

    In fact I have both versions, but i don't rely on 2.18 version as it is still have many issues. I always use the stable LTR release of 2.14.20. Until 2.18.14 becomes stable LTR I will use it. – ahmadhanb Dec 6 '17 at 4:57
  • I updated my answer. Actually both versions worked fine. What projection are using? I tested on projected UTM data as you can in the images above. – ahmadhanb Dec 6 '17 at 5:18

    Updated to latest 2.18.16 and the issue is not reproducible anymore. Thanks @ahmadhanb! Always helpful. – Kazuhito Jan 24 '18 at 14:02
