New commits: commit b0676e0ec9a770f83c19390d2d69df57bdb60d24 Author: Aron Budea <aron.bu...@collabora.com> Date: Mon Jan 23 03:47:19 2017 +0100 tdf#100151: Dispose of window if DX device creation failed Before, if the device lacked Direct3D capabilities, VclPtr handling became compromised, and caused a crash. This was particularly a problem in virtualized/remote desktop connections in Windows. Now mpWindow instance is disposed of right away if DX device creation fails.
