(In reply to V Stuart Foote from comment #7) > By zoom you mean the LibreOffice canvas zoom--and not the os/DE GUI scaling, > correct? Canvas zoom.. I assume Vulkan to be to powerful to notice the lag. Tearing is happening at GDI. Skia raster simply slows down (not smooth scroll, but with certain lag) I assume other backends being affected too. But have to check that (In reply to Roman Kuznetsov from comment #9) > https://gerrit.libreoffice.org/c/core/+/111893 Related to this: the document in tdf#140753 has a PNG which technically has an alpha channel, but it's actually completely opaque -> the image is created by LibreOffice, I inserted a PDF and saved it as DOCX. I'm asking myself is it actually desired to export alpha channel in cases where the image is completely opaque? Created attachment 170214 [details]

Another file showing slowness scrolling left/right top/down with some zoom-level set. I hope it's dealt with already... but well you never know.
I do not see any redraw problems with any of the documents. Please provide more info (such as a screenshot). (In reply to Luboš Luňák from comment #12) > I do not see any redraw problems with any of the documents. Please provide > more info (such as a screenshot). Have to look again.. You're recent commit https://gerrit.libreoffice.org/c/core/+/111893 improved things a lot already. I'm waiting for: https://gerrit.libreoffice.org/c/core/+/111966 and will re-test everything with different backends..
