Created attachment 1260204 [details] glxinfo Description of problem: I observe massive display corruption in blender with radeon driver / Gnome Xorg session: The whole interface seems to blink back and forth (triggered by moving he mouse around) between the current state and some state it had before the last interaction. As a result, when clicking a button or doing something that greatly changes the view, the interface will then blink back and forth wildly between the new state it should be in and what I saw before that interaction. Since the UI consistently reacts to the new state even when the old one blinks in between, this seems to be purely some sort of render corruption rather than some actual UI bug. Version-Release number of selected component (if applicable): [jonas@falcon ~]$ blender --version Blender 2.78 (sub 0) build date: 2017-02-13 build time: 20:34:46 build commit date: 1970-01-01 build commit time: 00:00 build hash: unknown build platform: Linux build type: Release build c flags: -Wall -Wcast-align -Werror=implicit-function-declaration -Werror=return-type -Werror=vla -Wstrict-prototypes -Wmissing-prototypes -Wno-char-subscripts -Wno-unknown-pragmas -Wpointer-arith -Wunused-parameter -Wwrite-strings -Wlogical-op -Wundef -Winit-self -Wnonnull -Wmissing-include-dirs -Wno-div-by-zero -Wtype-limits -Wformat-signedness -Wuninitialized -Wredundant-decls -Wshadow -Wno-error=unused-but-set-variable -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -fuse-ld=gold -fopenmp -std=gnu11 -msse -pipe -fPIC -funsigned-char -fno-strict-aliasing -msse2 build c++ flags: -Wredundant-decls -Wall -Wno-invalid-offsetof -Wno-sign-compare -Wlogical-op -Winit-self -Wmissing-include-dirs -Wno-div-by-zero -Wtype-limits -Werror=return-type -Werror=implicit-function-declaration -Wno-char-subscripts -Wno-unknown-pragmas -Wpointer-arith -Wunused-parameter -Wwrite-strings -Wundef -Wformat-signedness -Wuninitialized -Wundef -Wmissing-declarations -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -fuse-ld=gold -fopenmp -std=c++11 -msse -pipe -fPIC -funsigned-char -fno-strict-aliasing -msse2 build link flags: build system: CMake How reproducible: 100%, just launch blender and click something to trigger a UI state Steps to Reproduce: 1. Launch blender 2. Change the view / open a file / rotate the view / ... do anything that would require the UI to change Actual results: UI and views update correctly Expected results: UI and views update but blink back and forth with older previous state Additional info:
For what it's worth, this effect is always limited to purely the contents of the blender window itself. So it doesn't seem to be the gfx driver freaking out as a whole, but some blender-related problem.
