Created attachment 112788 [details] Various badly scaled textures in Jagged Alliance: Flashback I've noticed, that several Unity3D based games seem to have issues with scaling textures for high resolutions in menus. Dreamfall Chapters exhibits this in the load savegame menu, where the preview images of the scene are just a few large blurry pixels. Jagged Alliance: Flashback has this in the inventory, the command overlay (see the mini map or the merc data in the attached screenshot; ignore the blueish rendering, that's bug 88780). As soon as I reduce the resolution to, say, 1920×1080 from my native 2560×1440, everything looks fine.

This is a Unity3D bug. Unity is not detecting the right amount of VRAM for my card and was falling back to very low default values which caused it to downsize textures. This is fixed for Mesa-based drivers in Unity 5 and 4.5.5p5 (4981db1e7f9f), ie. all versions, that use GLX_MESA_query_renderer. Thanks to Levi from Unity Technologies, "Hand of Fate" developers from Defiant Development and Josh who helped resolving this issue.
