Not clearing the vdev made it draw on whatever garbage was left there from previous paints when the buffer was taken from maFreeBuffers in VDevBuffer::alloc, so since this was also the only place left that didn't clear the buffer explicitly, this makes the clear unconditional in impBufferDevice ctor. Also this makes sure to clear proper rectangle in VDevBuffer::alloc, and to clear mpAlphaVDev in OutputDevice::Erase. <a href="https://cgit.freedesktop.org/libreoffice/core/commit/?id=bf021c369f2306ee507da9bd3cc4cd10ac5d234c">https://cgit.freedesktop.org/libreoffice/core/commit/?id=bf021c369f2306ee507da9bd3cc4cd10ac5d234c</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
