When I resize window in any environment, sometimes I see strange anomaly, which lasts until more resize or mouse drop.
It's same in each environment and with all windows.
Here is it:
System: Debian 9 Stretch
Graphic card: Intel HD graphic 530
:~$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 530 (Skylake GT2) OpenGL core profile version string: 4.5 (Core Profile) Mesa 13.0.6 OpenGL core profile shading language version string: 4.50 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 13.0.6 OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 Mesa 13.0.6 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions:
Is there any known problem, which I should study or settings, which can repair this problem? Do you have any experience? Thank you.
