Description

17 years ago
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.7+) Gecko/20020108
BuildID:    20020108 21

Text jumps up and down when it is marked. See the attached examples and notice
the white space between the marked text.

Attached 2 pictures:
1. Space between marked text
2. No space between marked text

Attached testcase, a minimal version of http://www.devel.lyx.org/

Reproducible: Always
Steps to Reproduce:
1.Go to http://www.devel.lyx.org/
2.Make sure you see the "side navbar" and not the "top navbar".
3.Browser size eg. 800x800
4.Place the cursor in the text under "Current state of LyX" 
5.Mark the text moving the mouse slowly down and up and see how the text jumps.

Or as an alternative use the testcase.

I see this and have attached a simpler testcase.

Also, to reproduce with the new testcase:
1. start selecting at "site".
2. Drag select to the end of the first line
3. Drag select down to the second line.
(Both lines should be properly selected)
4. Continue dragging back to the left to the beginning of the second line.
(there should be a white line between the selected lines now)

The behavior seems dependent on the heading, which has a font-size of 1.727em. 
1.72em and 1.73em do not exhibit this behavior.
I can see the first line jump up as I select it, today's linux CVS.

Could this bug depend on the screen resolution?
I only see this bug in 1280x1024 (or 1280x960) mode.
I have tested the following resolutions:
1600x1200, 1400x1050, 1280x1024, 1152x864, 1024x768, 800x600, and 640x480.

BTW bug 104550 seems also to depend on the screen resolution.

The new test case works fine for me.  Just selecting text, right?

This strange behaviour disappeared somewhere between 1.2 and 1.3a.

the second testcase behaves the same as it did before, but the first one seems ok.

Did the new textframe have any effect on this bug? I bet it's gone by now, but I can't check without a working Linux box.

I used to see this bug every once in a while and haven't for a long time. I don't know for sure that it was new textframe, but I do think something fixed it.
All the tests WFM.  Firefox 43.0.3 on Linux64.
