tdf140349_pixel_spillover_top_bottom


two observation(s):
		
	a) the slight spillover of pixels across their borders happens for all four of them, left, right, top and bottom.
	   under 'Format' -> 'Paragraph' -> 'Area' -> 'Gradient', modifying the values of 'Angle' and 'Border' reveals more about the behaviour of this bug.
	   changing the value of 'Angle' from 120 degrees to 270 causes the same spillover of pixels across the top and bottom borders.
	b) in order to repro -> make the pixels spillover their borders,
		1) scroll down to footnote 2 and zoom into the maximum limit.
		2) on the scrollbar using the 'scroll thumb' or the 'knob', repeatedly scroll from left to right and reverse. (to go back and forth)
		3) repeat scrolling and reverse scrolling a few times, the pixels will spillover their borders. 
		4) the same happens for [120 degrees] < 'Angle' value < [270 degrees] and top to down scrolling and reverse. 
		5) repeat scrolling and reverse scrolling a few times, the pixels will spillover their borders.

Dear Telesto,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
