[Libreoffice-bugs] [Bug 98500] Multiple animated GIFs cause 100% CPU utilization in Impress
https://bugs.documentfoundation.org/show_bug.cgi?id=98500 Dwokfur changed: What|Removed |Added CC||at...@atoth.sote.hu --- Comment #4 from Dwokfur --- Created attachment 126627 --> https://bugs.documentfoundation.org/attachment.cgi?id=126627&action=edit Sample slides with animated gifs to demonstrate the problem I'm suffering from this bug for a long time now. It forced me to switch back to OO. Please take a look at on the sample slides I've uploaded. There's not so much problem I can see in EditView. Now try to enter into presentation mode. It gets unusable. Try switching slides: painfully slow. The animations are constantly lagging: they are jerky and lumpy. It happens to me using either x86 or x64 versions of LO 5.1.x or 5.2.x on Win 7 64bit. Also experience the same symptoms with LO x64 on Gentoo Linux 64bit - compiled from source. The same time OO 4.x binary performs well. Now please load the same slides in OO 4.x or some old LO 4.x install! This is how it should do. The presentation is smooth and the transitions are nearly instant. The animations are well synchronized. This is a regression introduced long time ago and I wish it will be corrected, unless I cannot use this otherwise nice piece of software and should stick with OO 4.x or old LO installs. Another remark: the background image looks pixelated in either EditView or during presentation. Just check out how much better it can be in OO 4.x or old LO. I'm sorry to say, but LO 5.x Impress in its current form is simply useless to me and I'm quite worried about the future.

I tend to disagree. I installed an LO 4.x to test the same presentation. Although it was sluggish at the beginning, I was able to edit the last slide of my presentation - move around GIF, add text box with text, move it around etc. It only shows that much higher performance is possible as it was provided by an older version of LO. Tested file: "Presentation with multiple animated GIFs causing LO Impress slowdown" Tested versions (installed in parallel with identical settings - any hardware acceleration disabled): Works quite good, although switching between animated slides in edit mode is with a delay (it takes time to load image). Version: 4.4.7.2 Build ID: f3153a8b245191196a4b6b9abd1d0da16eead600 Epic Fail - after some minute of light editing of last slide, LO slowly gets unresponsive (window content is not repainted any more). Pauses between window content repaints get longer and longer till it is not possible to close LO in a normal way and killing it is the only option. Version: 5.2.0.4 Build ID: 066b007f5ebcc236395c7d282ba488bca6720265 CPU Threads: 2; OS Version: Linux 4.7; UI Render: default; -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

I think noone wants > that back... In LO 4.4.7.2 I could add two overlapping animed GIFs + text boxes and other drawn figures in front and back of GIFs - partially overlapping them. No rendering issues in Edit or Presentation mode. I was able to edit the presentation (ok, slide switching is slow). In LO 5.2 I even can not get that far to add second GIF, not talking about adding boxes etc. If there is a choice between kill -9 soffice and objects ignoring rendering hierarchy, I fail to see any advantage of "the correct way of doing things". If it helps to track the real issue, it seems that the condition is caused by hovering with mouse over animated GIF (a normal action while editing a slide). As long as there is no interaction with animated area, LO 5.2 is running fine. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

Couldn't repro the crash with LO 5.1.0.3, so it could just be a quirk of this 5.2 daily build. TODO: Check with latest daily build of master.
