valgrind output

For convenient debugging, go to unigine-heaven/bin and run

I'm using GALLIUM_HUD=sensors_temp_cu-amdgpu-pci-0100.temp1 for this.
glxgears works fine with it.
ungine-heaven crashes (I have not tested more applications).

For convenient debugging, go to unigine-heaven/bin and run

./heaven_x64 -project_name Heaven -data_path ../ -engine_config
../data/heaven_4.0.cfg -system_script heaven/unigine.cpp -sound_app openal
-video_app opengl -video_multisample 1 -video_fullscreen 0 -video_mode 6
-extern_define ,RELEASE,LANGUAGE_EN,QUALITY_HIGH,TESSELLATION_NORMAL
-extern_plugin ,GPUMonitor

after printing
Set 1920x1080 windowed video mode
it crashes
*** Error in `./heaven_x64': corrupted double-linked list: 0x0000000001d7b040
***
