[TxMt] Large file does not properly paint text when scrolling in v2.0 on MacOS Catalina

[Gregg Kellogg]

I created an issue for this in github.com/textmate/bugs (https://github.com/textmate/bugs/issues/33), but perhaps that issue tracker isn’t monitored any longer.

After upgrading to MacOS 10.15 (Catalina), scrolling through a large file (>6000 lines) often does not properly paint the text. This can be temporarily corrected by dragging a selection over the missing text.

	• OS version: MacOS 10.15 (Catalina)
	• Textmate version: 2019-09-15 (v2.0)
	• Affected file: https://github.com/w3c/json-ld-api/blob/master/index.html.
	• File language: HTML
Most recently, I noticed this when moving to line 3500 in the referenced file and scrolling downwards.
