LO Version: 18.104.22.168 Calc Linux Mint 18.1
On spreadsheets which already contain data, when I enter text into a new cell, the text becomes thick and obscures what it is that I am typing until I hit ‘Enter’ or tab and then clears itself. On occasion when scrolling through a large spreadsheet, rows are turned black, but again clear themselves.
This is happening on two different machines, both running Mint (one 18.0 the second 18.1). The 18.1 version uses Mesa DRI Intel graphics card with 1920x1080 pixel resolution, version 1.18.4. The kernel is Linux 4.4.0-53-generic (x86_64)
I’ve done extensive on-line searches and cannot find any mention of this, so perhaps I’m using the wrong language/ terms?
