Created attachment 137572 [details] video showing the behavior during editing This occurs systematically in this context : - Debian 8 jessie, whatever the version of the graphic card driver - PC with 5th generation Intel CPU (Broadwell) and not with 4th generation intel CPU (Haswell) - big spreadsheets (size > 5 Mb) - LibreOffice 5.2.x, 5.3.x, 5.4.2 The small video attached shows what users see. Some tests have been done : - Enabling OpenGL improves the behavior but Calc becomes very slow, so slow that it can't be the answer - the redraw function fixes the display - disabling AutoInput improves the behavior, because no other word is displayed below the words typed. But users need AutoInput and it doesn't really solve the problem. - aggravating factor : centering text in a cell makes the cell completely unreadable while editing This bug is maybe linked to this one : https://bugs.documentfoundation.org/show_bug.cgi?id=108812
As in bug 108812, could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ? You can install it alongside the standard version. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build

As you can see problem still occurs with master_2017-11-13_22.41.23_LibreOfficeDev_6.0.0.0.alpha1_Linux_x86-64 on Debian 8 Jessie (up-to-date). (In reply to Mathias Blanchemanche from comment #2) > Created attachment 137805 [details] > ghosting characters problem FYI everything works fine on Debian 9 Stretch with LibreOffice 5.2.7.2 20m0(Build:2), that's the standard version from the debian repos.
