Created attachment 118139 [details] Black layout options in libreoffice impress After upgrading mesa to 10.6.0 or later, some graphs in libreoffice impress became black squares. It also happened on some background images so some slides just became totally black. Per my bisect result, the first bad commit is this one: commit cf6f33ee68ca56df1650762634fa9c038359c3ec Author: Eduardo Lima Mitev <elima@igalia.com> Date: Thu Mar 12 08:16:09 2015 +0100 mesa: Check for valid PBO access in gl(Compressed)Tex(Sub)Image calls Theoretically, this commit should impact every graphic driver, but I only got this issue on the system with Radeon HD 7770 vga card. The other system with only intel vga card (with mesa 10.6.2) displayed everything as expected, so it's likely to be a bug in the radeonsi driver. I also found a similar issue in a gtk program(*) which draws a white line with cairo but the whole became black after upgrading mesa. Here are the lines suffer the problem: src/core/caret.cpp: void CCaret::DrawInverse() if (m_Cairo == NULL) { m_Cairo = gdk_cairo_create(m_pParent->window); } cairo_set_source_rgb(m_Cairo, 1, 1, 1); cairo_set_operator(m_Cairo, CAIRO_OPERATOR_DIFFERENCE); cairo_rectangle(m_Cairo, m_Pos.x, m_Pos.y, m_Width, m_Height); cairo_fill(m_Cairo); Hope this can help to narrow down the scope.
