Comment 2 Dieter Nützel 2016-11-03 03:08:54 UTC 
Fix is underway.

Have a look at Mesa-dev:
https://lists.freedesktop.org/archives/mesa-dev/2016-November/134137.html

src/gallium/winsys/radeon/drm/radeon_drm_surface.c

-    if (!(surf_ws->flags & RADEON_SURF_IMPORTED)) {
+    if (!(flags & (RADEON_SURF_IMPORTED | RADEON_SURF_FMASK))) {

A combination of Marek's idea plus Michel's patch
[Mesa-dev] [PATCH 3/4] gallium/radeon: Use flags parameter in radeon_winsys_surface_init

SOLVED

both (FreeCAD and LS2015 on Wine) for me.
Comment 3 Marek Olšák 2016-11-05 17:37:33 UTC

Comment 4 Dieter Nützel 2016-11-05 19:08:51 UTC
