Created attachment 169151 [details] demo slides LO Impress is laggy and slow when opening a presentation that has a very complex theme. In my case the background of the slides is made with numerous objects and transparency layers. This seems to slow down Impress significantly. Try changing between slides and/or typing into the boxes to see how laggy it is. Extremely often the whole application gives Not Responding message and hangs. CPU usage is above normal, around 25% for LO Impress only. Use the attached file as a demo. You can inspect the master slide to see the background theme for the slides. ===================== Version: 7.1.0.2 (x64) / LibreOffice Community Build ID: 53d68d29d90fd16448721a60aad68c28ff0809f5 CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win Locale: ro-RO (ro_RO); UI: en-US Calc: CL
Thank you for reporting the bug. LO Impress does not slow down after opening presentation. CPU usage is also normal. I can not reproduce the bug in Version: 7.0.3.1 (x64) Build ID: d7547858d014d4cf69878db179d326fc3483e082 CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL Version: 7.2.0.0.alpha0+ (x64) Build ID: 761a672d62df1891b9f4f367a499b220ab2b33fa CPU threads: 4; OS: Windows 6.3 Build 9600; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL
Not seeing much slowness except zoom/in out (which is also not good)
Hello Mihai Vasiliu, I believe this issue might be fixed now after https://git.libreoffice.org/core/commit/27a4aea50a9efa5c839b0ae2de1f9f14a7782f11. Could you please try to reproduce it with a master build from http://dev-builds.libreoffice.org/daily/master/ ? You can install it alongside the standard version. I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the master build
Thanks a lot for the update. I tested with Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community Build ID: 28555fc345ac2ccdda0e4e0f3c812c646befe68b CPU threads: 8; OS: Windows 10.0 Build 19042; UI render: Skia/Raster; VCL: win Locale: ro-RO (ro_RO); UI: en-US Calc: CL and I can confirm it is fixed. The presentation works snappy. LO Impress does not hang anymore.
Thanks for rechecking. Closing as dupe of bug 138068 *** This bug has been marked as a duplicate of bug 138068 ***
