on bug 98351
from Tomaz Vajngerl
Hi, I'm the guy that works on the OpenGL code in LibreOffice and I have the same problem on my machine with radeonsi. The problem is with area scale shader [1] (which is used for scaling images in the document) - more specifically with the arrays at line 51, 52, 54, 55. I changed the scale algorithm to not use any arrays but this still seems to be nouveau to the OpenGL driver as the shader works as expected with intel or nouveau driver as well as nvidia and amd drivers on windows, but OTOH not intel driver on windows. I also managed to get it working if I reduce the array to 16 or less. [1] https://cgit.freedesktop.org/libreoffice/core/tree/vcl/opengl/areaScaleFragmentShader.glsl?h=libreoffice-5-2-3#n51
