* lib/RELEASE-NOTES
It would be nice if someone involved in numerous dicussions about
various bugs under different Qt 5.x versions wrote summary paragraph...
We have the following in RELEASE-NOTES:
* LyX 2.2.0 and the following 2.2.x releases will continue to work well with
Qt 4.5 (and later Qt 4.x) but will also support Qt 5.6, which brings some
advantages most notably for users with HiDPI displays. Note that if you
compile LyX with a Qt 5 release before 5.6 you are likely to run into
several regressions with respect to Qt 4.x. See #9215 for a list of bugs
related to compiling LyX with different versions of Qt.
I think it is sufficient. The nice thing is that we can add more
information to #9215 after release if we want since we reference it.
Do you know any other bug on Linux+qt5.5.1 than
http://www.lyx.org/trac/ticket/9731 ?
Not offhand but I'm sure there are some that I cannot remember. I might
look through our bugs with "qtbug" keyword and improve #9215.
Because on the other hand with qt4 there is the critical
http://www.lyx.org/trac/ticket/9362. I also noticed that lyx is very slow
with qt4 now, with profiling showing that most of the time is spent in
QTextLine::setLineWidth() below GuiFontMetrics::breakAt(). In fact I find it
more annoying than #9731, so much that I switched to 5.5.1.
Is the above with 4.8.6? Is there a chance that 4.8.7 has improved
something?
I noticed this starting with 4.8.7.
I wonder whether
LyX 2.2 should not be built with qt >= 5.5.1 on Linux when possible.
For these reasons as well, I am hoping that for 2.3 the community of LyX
developers will choose to focus on qt >= 5.6.
+1
Note that Ubuntu 16.04 shipped Qt 5.5.1 and that will be around for a
while. It would be nice to test our LyX with that Qt version as well.
Yes, one can expect feedback from this version as well.
