[Bug 158963] LibreWriter lags when spread across multiple screens.
https://bugs.documentfoundation.org/show_bug.cgi?id=158963 --- Comment #8 from Adam --- Per Buoyjaga's suggestion, I have installed and tested version 26.2. I did not experience any lag across screens, even after opening multiple documents on both monitors. *However* Initially, in dark mode, highlighting was not working on either monitor. While the text would be selected (per test results), it would not be shown as highlighted. I considered that this might be a fault in color selection for highlighting in dark mode, and clicked on the Tools drop-down, only for the drop down to show as all white with no (visible) text. As this did not match my results from using the drop down menu in dark mode a few minutes previously, I closed all but my initial test document, and tried again. This time it behaved as expected. But once I opened up a few new documents and spread them across screens again, neither the lack-of-highlighting nor the white drop down menu issues repeated. As this seems to follow the same 'can be trained out' behavior as I described previous, but minus the lag symptom, I believe this has the same root cause. The lack of highlighting issue is one I had previously (in primary build) with documents on two screens, but I had assumed that it was a side effect of the lag issue. There have been no changes to my hardware, and I am still running Windows 10.

It would be interesting to hear how it works, if you install Win-x86_64@tb77-TDF from https://dev-builds.libreoffice.org/daily/master/current.html -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=158963 --- Comment #5 from Adam --- At this point in time, I am not getting any lag with or without the spellchecker or skia options. However, with skia off, and two documents on the second monitor (and six open in total), the toolbar icons flash on and off in a fast pattern from left to right, but only on the top document of the two on the 2nd monitor. This did not reoccur when I turned skia back on. And upon turning skia back on and restarting the program, I got lag again when splitting the documents. And repeated. So something 'remembered' being 'trained' out of lagging, until I turned skia off and back on. And I just tested, a few runs of moving a document between monitors and typing a few letters each time and the lag gets 'trained' out again. I do not know what is actually happening, I am using 'trained' as an analogy for what seems to be happening. -- You are receiving this mail because: You are the assignee for the bug.

Can you please test to see if the lag depends on: - automatic spellcheck? (turn it off in Tools > Automatic Spell Checking) - Skia? (turn it off in Tools > Options > LibreOffice > View. Your version info should then read "UI render: default") -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=158963 --- Comment #3 from Adam --- I just reproduced it using the new version, though it was less sever. I opened two documents, and created a new one to test with. With all documents on the primary monitor, there was no lag. When I moved one of the opened documents to the second monitor, I had about 2-3 seconds of lag, which went away when I moved the document back. This repeated when I moved the document over a second time, but the third time I moved the document over, there was no longer an occurrence of lag. To be clear: I was retesting by moving only, not by re-opening all the documents. New test: close all documents and repeat. Result: Lag again, but moving the document back, testing, and moving it to the second monitor again did not result in further lag. I then moved document 1 back to the primary monitor and moved document 2 over instead, and once more I had lag while writing in the new document. So it seems to lag less badly and recover more quickly than in the previous version, but it still happens.

https://bugs.documentfoundation.org/show_bug.cgi?id=158963 --- Comment #1 from Adam --- And I forgot to add that it is intermittent. I just tried to recreate it so that I could screenshot my task manager, and I just got small performance spikes that quickly died down again. So sometimes that small spike trips over something? Also, dragging the offending document back to the same monitor as the rest of them undoes the lag effect. -- You are receiving this mail because: You are the assignee for the bug.
