Description richardpeters 2015-09-08 16:37:10 UTC
There is a very significant delay from the time a key is pressed until the character appears on the screen.

The video indicated in tdf#94036 (https://www.youtube.com/watch?v=zBtF0od8VQg) shows the pb.
Comment 3 Michael Meeks 2015-09-08 20:52:42 UTC
Almost certainly an idle-rendering issue; personally I really wonder if the re-rendering shouldn't have a higher priority than anything 'MEDIUM' - then again; significant lag is rather curious; I'd expect this to be done & on-screen in ~1ms so. Julien & Richard - is this Linux or Windows or ? ...
Comment 4 Julien Nabet 2015-09-08 20:56:13 UTC
For Richard, it was MacOs, for the reporter of the dup, it was on Windows.
That's why I put All
As for me, with LO Debian package, it lags at the very beginning, then it's ok.
I noticed these logs with Debian package:
** (soffice:24988): WARNING **: missing get indicator state

On Windows 7 Home, LO, if I type a word quickly and immediately Alt+Tab to another application, the final letters of the word are lost.

Comment 7 krzema12+documentfoundationbugzilla 2015-09-23 21:18:33 UTC
I've just checked it on - no lagging. It's probably due to the OpenGL support, advertised in 5.0.2.
Comment 8 Björn Michaelsen 2015-11-23 22:17:39 UTC
Not trivially reproducable on Ubuntu 15.04 with 1:5.0.3~rc2-0ubuntu1 from the LibreOffice ppa => NEEDINFO for more specific repoduction scenarios

dupes say this is not Writer-specific, thus => Component: LibreOffice
