Description: This is occurring systematically. If I am working in a calc document that already has values in cells, and if I attempt to delete some of the text in a given cell that already has text/numbers in that cell, the display appears to "double" up on itself, generating a display error which makes editing the document difficult. I have included a screen shot to provide a visual example of what I mean. This appears to be a display bug of some kind. As soon as I finish editing the cell and press enter or click a new cell, the display corrects itself. Moreover, this behaviour only seems to occur during the "editing process" of data entry in a cell. This does not occur on the input line -- only in the cell. It happens at different zooms, with different fonts, etc. I have tried enabling and disabling OpenGL, refreshing my user profile, turning anti-aliasing on and off, trying both LibreOffice still and fresh builds -- but no luck. Steps to Reproduce: 1. Open a new or saved calc document and enter text in a cell 2. Delete the text you just entered in step 1 Actual Results: Text appears to double up on itself with a display bug in the cell that is being edited if edits were an attempt to delete previous text. Expected Results: The display bug should not occur. Reproducible: Always User Profile Reset: Yes Additional Info: User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0

Please test changing the state of Menu/Tools/LibreOffice/View - OpenGL
Enabling OpenGL leads my entire LibreOffice install to develop a different set of display problems. Writer, calc, etc. will launch, but the display flashes black in areas and the display is corrupted with movement of the mouse/keyboard. From what I can tell, the problem reported above is solved with OpenGL enabled (though it is hard to tell given the corrupt display); but unfortunately, that solution makes the overall experience much worse. Perhaps this is a different bug to be filed with respect to OpenGL?
Have you tested disabling all Graphics options, anti-aliasing and/or hardware acceleration?
Yes. I have tried enabling and disabling each option, as well as different combinations of them. No luck I am afraid. Strangely, this is the only bug I have encountered across all my libreoffice applications. All other use cases display correctly (writer/impress/etc.). It is just in calc in the cells during editing where this occurs.
Please try resetting the user profile, sometimes solves strange issues. https://wiki.documentfoundation.org/UserProfile Usually it's enough renaming/deleting the file "user/registrymodifications.xcu", it affects all the options in Menu/Tools/Options, and the files "user/basic/dialog.xlc" and "scrip.xlc" are overwritten, additionally custom colors in "user/config/standard.soc" are lost.
Or test disabling the option Menu/Tools/LibreOffice calc/General - Use printer metrics for test formatting.
I have tried resetting my user profile a number of times, and even reinstalling Libreoffice from scratch -- sadly this did not resolve the problem. I then tried the "Use printer metrics for test formatting" suggestion. I had that setting off by default, so I enabled it instead. Regardless of whether it is enabled or disabled, the same problem persists.
Maybe testing with a dev version, to verify the issue is yet there: http://dev-builds.libreoffice.org/daily/master/
I wanted to report that this issue has been resolved -- the display error no longer occurs. I am not sure what changed to fix this. Perhaps the latest version of LibreOffice, or perhaps upgrades to Mesa? Regardless, I am very happy to say this issue can be closed.
Thanks for the information. Then closed as works for me.
