Vlad Zahorodnii	617650d440	[scene] Discard pixmaps on buffer size change ... The surface size is a logical size, which renders it unsuitable for deciding whether the window pixmap needs to be discarded. We need to discard window pixmaps when the buffer size changes. That has a drawback though, discarding textures is kind of an overkill with linux-dmabuf. However, fixing that would involve changes in kwayland server that are far from being trivial.

Vlad Zahorodnii	4a681e3d47	[scene] Discard quads when the surface-to-buffer matrix is changed ... The surface-to-buffer matrix provides a generic mechanism for mapping things from the surface-local coordinate space to the buffer coordinate space. If it changes, we know for sure that the texture coordinates have to be re-computed.	2020-06-19 06:45:33 +00:00
Vlad Zahorodnii	9bfcfb7f74	[scene] Rebuild window quads when sub-surface tree changes ... Sub-surface contribute to the window quads cache. So, we must re-build it, if any sub-surface has been changed. Differential Revision: https://phabricator.kde.org/D29131	2020-05-04 15:36:40 +03:00
