Bug 453048 – dev-lang/R-2.15.2 produces an empty plot window with buffered cairo

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description gordon 2013-01-19 22:11:38 UTC]

X11 plots are not drawn (i.e. the window stays blank) when using X11.options(type="cairo") and X11.options(type="dbcairo"). They are correctly drawn when using X11.options(type="nbcairo") and X11.options(type="xlib"), or after resizing the X11 window.

Reproducible: Always

Steps to Reproduce:
1. Run R
2. run demo(graphics)
Actual Results:  
Empty plot window

Expected Results:  
Plot window with graph

Seems that this bug appears with >=cairo-1.12 but not with 1.10
