| Latest Commit: | Version Fixed In: | 23.03 | |
It's updating the config file's saved data for the sidebar width. We should only do this on mouse release, not on any movement. I think this may be the cause for some other bug reports. Adding them to See Also. I reported Bug 441676 linked in the See Also section, and unfortunately the problem still persists with Okular 22.12.1. *** Bug 441676 has been marked as a duplicate of this bug. *** (In reply to geisserml from comment #3) > I reported Bug 441676 linked in the See Also section, and unfortunately the > problem still persists with Okular 22.12.1. Please don't change the Version field, which represents the _initial_ version which showed the issue. Unfortunately it's not possible to readd the previous value because it's tool old. For the record, it was 1.11.2. > Please don't change the Version field, which represents the _initial_ version which showed the issue.
Ah, that makes sense. Sorry!
Isn't this fixed along with BUG 455013? (In reply to popov895 from comment #7) > Isn't this fixed along with BUG 455013? Certainly looks like a nice change, but I can't tell if it will actually fix this issue (AFAICS, the topic resizing wasn't explicitly mentioned anywhere on that MR). If I'm not mistaken, the change is supposed to land in Okular 23.04? Yes, but you can already use an KDE neon Developer Edition to test it. @popov895 Ah, I just realized by name that you are probably the author of the MR yourself? If that's right, then thanks a lot for your work! I just installed the okular beta via kdeapps flatpak and can confirm that the bug is indeed fixed. Resizing is now super smooth again, as it used to be back in 2020. And of course it's nice the panel can now be moved. |
jbd2 uses an excessive amount of disk resources when resizing the sidebar. This is especially annoying on systems with HDDs, such as mine. iotop sample: Total DISK READ : 0.00 B/s | Total DISK WRITE : 103.08 K/s Actual DISK READ: 0.00 B/s | Actual DISK WRITE: 1104.06 K/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 1095 be/3 root 0.00 B/s 0.00 B/s 0.00 % 81.14 % [jbd2/sda7-8] 13819 be/4 root 0.00 B/s 0.00 B/s 0.00 % 0.43 % [kworker/5:0-events] 13266 be/4 slau 0.00 B/s 103.62 K/s 0.00 % 0.25 % okular I/O goes back to zero when I release the click. STEPS TO REPRODUCE 1. Open Ocular 2. Click on the sidebar and drag it side-to-side (with or without a document opened) OBSERVED RESULT brrrrrrrrrrrr SOFTWARE/OS VERSIONS OS: openSUSE Tumbleweed KDE Plasma Version: 5.20.0 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 Kernel Version: 5.8.14 Display Server: X11
