Description Clemens Eisserer 2013-06-25 17:52:19 UTC

Resizing applications so that their width exceeds 8192 px results in black areas.
Tested on my SNB Laptop and XFCE without a composition manager.

The application which showed this behaviour is Thunar file manager (1.6.3) using the mist gtk2-theme.

This has absolutely no priority for me, just thought reporting it doesn't hurt.
