Description: Vertical text on Y axis becomes almost unreadable, like it has no anti-aliasing at all. This problem occurs only when OpenGL is enabled in Calc. It can also been seen when exported as a PNG file. When opening a .odc file in "LibreOffice Chart" there are no issues. I've faced this issue also on branch 5.3.x. Might be persistent in earlier versions as well. OS is Windows 10. Steps to Reproduce: 1. Create a chart from data in LO Calc 2. Add a title to Y axis 3. Accept changes Actual Results: Text on Y axis is almost unreadable, no antialiasing is applied. Expected Results: Text should be readable. Reproducible: Always User Profile Reset: Yes OpenGL enabled: Yes Additional Info: Please see the initial report: https://ask.libreoffice.org/en/question/139601/problems-with-rendering-vertical-text-in-charts-unreadable-text-with-no-anti-aliasing/ User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
