Using GTK3 on Linux or default rendering on Windows, the issue started to happen after https://cgit.freedesktop.org/libreoffice/core/commit/?id=9d89d98d3349502b56da4bdd6ea287ac4cde9ce5 author Luboš Luňák <l.lunak@collabora.com> 2021-02-10 17:15:19 +0100 committer Luboš Luňák <l.lunak@collabora.com> 2021-02-12 11:18:09 +0100 commit 9d89d98d3349502b56da4bdd6ea287ac4cde9ce5 (patch) tree 4858b412c5322a9a6f23ea191dba40143b520649 parent f52c5bea7775ac07cfacc232f0979a03bbdf9aa7 (diff) always optimize bitmap transform to translate+scale if possible (tdf#138068) Bisected with: bibisect-linux64-7.2 Adding Cc: to Luboš Luňák

I thought this was on purpose, for solving that bug.
@Xisco Would a meta-bug be helpful? There are bunch of bugs pointing to the same commit

This issue is fixed by author Luboš Luňák <l.lunak@collabora.com> 2021-03-04 15:35:44 +0100 committer Luboš Luňák <l.lunak@collabora.com> 2021-03-08 13:46:36 +0100 commit 6b8c157a0b4f37a09fdbf656919b2df06a3abc3e (patch) tree 52451b3b5152511cb4fb68a2f09867bc9db85592 parent db2e9619397f1e53232824a649b5ad0ba3dd368a (diff) make RenderMaskPrimitive2DPixel() clip using clipping (tdf#140797)
If my change "fixes" this, then it's rather just worked around. Rotate the image slightly, that should still use the old code path and the problem should be still there. Also the impBufferDevice class is used in other places, so those may be possibly also affected.

Maybe it also fixed some other reports...

I rotated attachment 167713 [details]'s image by 2 degrees. It looked relatively good in 7.0, and didn't seem to be affected by Mike's 7.1 patch (comment 3). Marking as FIXED again. A problematic sample document would be needed to re-open.
