2582 - Scrolling selected text yields appended char. gunk at EOLs

Status: VERIFIED FIXED

(Core Graveyard :: Viewer App, defect, P2)

Description

[Eli Goldberg]

* TITLE/SUMMARY
Scrolling selected text in Viewer yields appended character gunk at EOLs

[seems like should be a known bug, but can't find any searching for "scroll",
"select", or looking through mjudge's bugs.]

* STEPS TO REPRODUCE
0) Launch Viewer
1) Select a bunch of text on a web page (I've used both the test0.html page, or
the simpler www.macfixit.com web page; just a few sentences will do.)
2) Scroll downwards, until the selected text is no longer visible.
3) Scroll back upwards.

* RESULT
 - What happened

The right-border of the selected text is appeneded with lots of character junk
that looks like random memory, mostly repeated identically on each line. (i.e
text from other <P>s on the page, or just unintelligible crud.

Crud changes each time you resize the window, and repeat steps 2 & 3.

 - What was expected

No unwanted appendages (so to speak).


* REGRESSION

 - Occurs On
        viewer (1.22.99 optimized build for Mac OS)
        viewer (1.21.99 optimized build for Win32 [NT 4, Service Pack 3])

 - Can't Reproduce On
        viewer (1.22.99 optimized build for Linux --- can't select text ;)


* CONFIGURATIONS TESTED

- [Mac] Power Mac 8500/120 (233 Mhz 604e), 64 MB RAM (VM on; 1 MB of VM used),
1024x768 (Thousands of Colors), Mac OS 8.5.1

- [Win32] Vectra VL (233 Mhz P2), 96 MB RAM, 800x600 (True Color), NT 4.0 SP3.

Looks like a rendering bug for you. I suggest you confirm this, then discuss it
with Pierre or DonC.

Setting all current Open/Normal to M4.

Comment 3

[Eli Goldberg]

This no longer takes place using the 2.8.99 Mac OS build or 2.4.99 Win32 build on
either of the cited sites.

Thus, I'm going to mark this as Verified/Fixed. (Please re-open if this
conclusion is in error; thanks!))
