Hello, thank's for your time reading this. I use wine(playonlinux wine 1.6.1) + 32 bit opengl libs (no closed-source drivers) for an application (game). (It runs almost perfect on debian 8 (jessie)) If I dist-upgrade to debian 9 (stretch) game has campaign map textures problem which make it almost unplayable. I can't find where the problem is, to provide more help. I would like to dist-upgrade. thank's.
