And the bigger jump after such freeze is. One more question: Does it occur when the *only* thing on the screen is the inset? As I said, I suspect that something weird happens with the metrics calculation here. Either that, or there is some reason we paint the screen multiple times, and maybe that is slower on Wayland. It is worse on Wayland? Riki -- lyx-users mailing list lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users

So it's at least not the other issue I had in mind. Do you also see this with other insets? E.g., footnotes? Does it matter if the top of the inset is still on screen? Or if the bottom is off? Does the inset need to be bigger than the screen for you to see this? JMard will know better than I, but I think there may be something weird that happens once an inset spans the whole screen. Riki Inset must be really huge to see big sluggishness. If it is bigger than screan, let's say, is like 7 screens long), I hear spike of CPU and see some sluggishness, if it is like three screens, I hear spike of CPU but see no sluggish. I created Lyx note, greyedout, comment, marginnote and footnote – the same behaviour. Yes, inset mus be bigger, but it doesn't matter is the top or bottom of the inset on screen. Text scrolls evenly until top or bottom of inset appears on screen, then CPU spikes and text jumps – stops – jumps. After inset disappears, text scrolls evenly. To be more precise, text scroll evenly and then stops when I even don't see inset – as I understand, it stops when inset should appear on screen if scroll would continue at the same speed. So I don't see inset and some normal text before or after inset. The bigger is speed of scroll, the bigger portion of normal text before or after inset I don't see too. And the bigger jump after such freeze is. As a total noob I see problem with "painting" of inset. -- lyx-users mailing list lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users

The faster scroll, the higher CPU usage, but document moves very slowly and with quite a big delay and with big jumps. wayland can be the culprit. I opened lyx in xwayland mode and I can scroll through the note only slowly – after scrolling fast document are thrown back to initial position. CPU usage about 70%. In wayland – 99% if scrolling is intensive, up and down. -- lyx-users mailing list lyx-users@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-users

Re: outline pane issues and huge note slowness
Le 04/02/2021 à 01:15, V K a écrit : Hello. Lyx is approaching 2.4 and I want to draw attention of devs to the outline pane functionality and problem of the huge notes. Maybe some of these issues can be fixed relatively easy and quickly till the new release. These issues probably deserve their own tickets on trac (either grouped or separated). Concerning the performace issue, it is a known problem which is generally not as bad, but it will be difficult to fix before 2.4.0 IMO. I would appreciate to have a file to play with (you may want to use buffer-anonymize on it). JMarc 1. "Keep" tikbox in the outline pane is working inconsistently. Let's say, I opened all navigation tree elements by sliding bottom slider of the outline pane to the right and ticked "keep". It's keeping tree while I am navigating through the document, but after going to another document and coming back I see collapsed tree (ticbox is still ticked). This situation is particularly discomfortable when working with master-child documents. 2. Navigation tree in the outline pane collapses after ctrl+z (undoing) while "keep" is still ticked. 3. Situation with notes and footnotes selection in outline. I am using Lyx notes, greyedout and comments severely while preparing texts. And it is very common situation when I want to go through all or some notes to correct text, delete notes. So I open notes list in the outline, search note I need, go to text to correct it and... all notes disapper in the outline and I see navigation tree there. So I must open notes list anew, select next note and so on. Ticking "keep" tikbox do nothing. Maybe such behaviour is intentional (to search only one note and automatically go back to navigation tree), but maybe "tickbox" can be used to keep notes list? 4. This isn't related to outline pane. My notes can be huge (to hide parts of the text temporary) and navigating in such huge notes is painfully slow, CPU usage rises dramatically (99% of one of the cores of the CPU). Such slowness presents only when huge note is opened and is visible in Lyx work area. Slowness disappears after collapsing note or after scrolling till it disappears from work area. The same problem is with big branches. Such slow was note with 75 000 characters (incl. spaces), more smaller notes and a lot of citations in it. Such situation is with master (bit dated – Built from git commit hash 9e1db659) and with stable too, as I remember. Thank you for your hard work – it is much more pleasant to work with Lyx office than with traditional offices.
