[Bug 1846940]
I tested today's build: https://dev-builds.libreoffice.org/daily/master/Win-x86_64@tb77-TDF/2019-11-05_05.07.09/LibreOfficeDev_6.4.0.0.alpha1_Win_x64.msi and the fix works also for me. Could this fix be included in the 6.3.x series too. I would consider this as quite important bug fix, and from the amount of duplicate bugs, it seems to have affected quite a few. In addition, the fix seems to be quite unintrusive and it fixes a regression introduced in this series. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846940 Title: [upstream] Loop in libreoffice-calc when scrolling to top of spreadsheet To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1846940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Very interesting to read about your bug hunt Armin, and good to see that you have made so much progress. About your A/B solution options. Is there any performance issue to consider, how often are these called in worst case scenario. I mean checking a flag sounds potentially more slower than just systematically adding the offset. Just my 2 cents, great work! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846940 Title: [upstream] Loop in libreoffice-calc when scrolling to top of spreadsheet To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1846940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

When I searched the originating commit from Github: https://github.com/LibreOffice/core/search?q=d464d505fbf6e53a38afdd3661d320fac8c760d6=Commits I noticed that developer vmiklos had fixed a similar issue as this bug: tdf#123505 svx: fix invalidation loop caused by special form control … https://github.com/LibreOffice/core/commit/5b51aa12e8ebfa894ecfdd0c8c9004aa99e6f46d Is there some way to ask if he could look in to this issue too. It seems very similar to the one he already worked on and is related to the same originating commit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846940 Title: [upstream] Loop in libreoffice-calc when scrolling to top of spreadsheet To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1846940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I believe that I have also stumbled on this bug and it seems to be very cumbersome to trigger. In my experience this bug triggered more by non-uniform row height than column width. Can anyone else trigger this bug with uniform column width and non-uniform row height? Also in my case, forcing uniform row height does fix this issue. Even if you change the height of some row afterwards. But it is only fixed for the current zoom level. If you change the zoom level, the flickering will come back on some other zoom level. Now the bug just manifests itself on a different zoom level than previously. Also, in some situations all of the menus and dialogs show up empty, while this bug is active. On multiple occasions, I have been able to trigger this with just one form control, but for some reason I can not find a pattern that would work always. With two controls it is more consistent, but with two controls I have not experienced the disappearing of menus and dialogs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846940 Title: [upstream] Loop in libreoffice-calc when scrolling to top of spreadsheet To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1846940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Adding to previous that if you enable: “Options > LibreOffice > View > Use OpenGL for all rendering” There is no flickering, but menus and dialogs show up empty. CPU use is high and GPU is 98%. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846940 Title: [upstream] Loop in libreoffice-calc when scrolling to top of spreadsheet To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/1846940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
