macOS: first painting of text-viewer shows upside-down text

[Alexey-T]

OSX 10.11 El Capitan.

• run Cud
• close all text ui-tabs
• hide bottom panel + side panel of CudaText (it's needed)
• call from 'Help / Command palette': open file, in text viewer. file-open dialog shows. Choose some binary file, e.g. dmg installer, I choose cudatext*.dmg.
• area of text viewer shows upside-down, until second repaint (e.g. until you resize the window)

@JairoMartinezA , I still did not repair my Mac setup in VM. maybe you can reproduce the problem (with older lazarus), then apply the lazarus patch, and see that it's fixed. you can reproduce it using the demo program attached in Gitlab issue.
