Description Andrzej 2013-12-10 00:10:13 UTC
These two functions (_color_lighten, _color_selected):

trigger an X error:

BadValue, error_code 2 request_code 155 minor_code 8

on call to cairo_mask.

Tested on RHEL5 (AFAIR, RENDER version is 0.09) with cairo 1.12.2 installed in $HOME. All blend mode operators I tried were failing, all simple ones (CAIRO_OPERATOR_ADD etc) worked fine.

Xfce (thunar) bug report:

Comment 2 Andrzej 2015-01-18 11:47:11 UTC
Any progress on that?

AFAIR the issue was that Cairo was not detecting RENDER version correctly and was trying to use unsupported blend mode operators.

Because of this issue we (Thunar) have to avoid more complex operators altogether because they crash the application on older X servers.
