Entire text line blinks in solid black on each character typed (OS X)

[zapta]

Update: The issue was introduced with QScintilla 2.9. It looks like they updated a bunch of lexer stuff, which we use for syntax highlighting.

Using Mac OSX 10.10.5 and upgraded recently to OpenScad version 2015.03-2 (got the upgrade notification so I assume I had the latest version previously).

Whenever typing text in the editing window the entire line blink with solid black. That is, on each character that I type, the entire line (including the background) blinks in solid black.

This is non usable. I will try to downgrade to the previous version.

I downgraded to 2015.03-1 and the problem disappeared. Seems to be a regression in 2015.03-2

OpenSCAD-2015.03-1 compiled with the latest dependencies still exhibit this bug, so it's caused by one of the dependencies. Likely candidates: QScintilla 2.84->2.9 or Qt 5.4.1->5.5.1

@donbright Could you give it a spin with QScintilla 2.9 if that's convenient for you?

[donbright]

cannot reproduce, QScintilla 2.9.1 linux

I've rebuilt the Mac binaries for 2015.03-2 with QScintilla 2.8.4.
Let's keep this open to track the QScintilla regression in 2.9

Fixed in QScintilla 2.9.3
