Bug ID: 1051083
Summary: Huge text rendered incorrectly
QA Contact: extras-qa(a)fedoraproject.org
Created attachment 847731
incorrect rendering (500K, all visible characters affected)
Description of problem:
When I open this (quite strange, I admit) file:
* ASCII plain text
* only dollar signs (no whitespace whatsoever, reproduces with other chars as
* large number of them (over 320K in my case)
in Mousepad, which uses pango, rendering issues appear. Specifically,
characters appear doubled, with these "ghosts" being few pixels offset.
I have tested this on Fedora 20 with Mousepad and Leafpad, both being
simplistic GUI plain text editors and both using Pango. Hence I'm reporting
this to Pango.
Version-Release number of selected component (if applicable):
always - with specifically prepared (abnormal) file
Steps to Reproduce:
1. Let N be a large number, 500 thousand or so (see below)
2. Create a plain text file comprised of N identical non-whitespace characters
3. Open the file in Mousepad or Leafpad
Characters are rendered incorrectly, some/all glyphs have a "ghost" with small
Characters should be displayed normally.
Exploring the exact border (N) where the problem appears:
* with 322,639 characters, the text still looks OK
* with 322,640 characters, first character has this "ghost"
* with 322,641 characters, first *two* characters have this "ghost"
I have also quick-tested this with other characters like "a", and the same
problem appears. I haven't tested with mixed files or with whitespace, though.
