This catches the case where the caption only contains a comment, as in export/export/latex/lyxbugs-resolved/cprotect/9313-comment-in-figure-float-caption. No duplicate work is performed to ensure the same level of performance as before.
Start a new directory of cprotect tests. There are many situations
where cprotect is needed so we can add files covering various
situations as we find them.
This particular test covers the case of special characters in URL
insets in footnotes.
The checkbox is hidden when backing store is enforced (wayland,
macOS). In practice, only X11 and Windows users will see it ; I only
have evidence of X11 people needing it, I can hide it for Windows
users too if necessary.
Fixes bug #12119.
LyX relies on a a backing store to draw when running under macOS or
Wayland, because Qt arbitrarily overwrites parts of the workarea
before we paint (and we paint only the parts that need to be painted).
However it seems that this is also necessary on X11 when the WM theme
is translucid. Since there is no way that I know of to detect this
situation, this patch adds a LyXRC setting to manually select this
drawing strategy.
Note that using a backing store is not always a good solution, since
this disables subpixel aliasing.
At this point there is no UI for the variable.
Fixes bug #12119
The default in the .ui is not considered in
GuiSearchWidget::restoreSession(), which sets a hard-coded default
if the stored setting is not found in the session file.
I'll start an ML discussion for whether the code in restoreSession()
should use the ui's default if the setting is not found in the
session.
Noto Sans Tibetan was not actually a sans font. On newer systems the
font is now Noto Serif Tibetan.
See, e.g., the package 'fonts-noto-core' in Ubuntu 21.04.
This change also fixes compilation of
supported-languages_polyglossia-XeTeX.lyx on Ubuntu 21.10.
For some reason, Qt can break strings before the first character
(although we try to prevent that). The code was not prepared to that,
now it is.
Remove a forgotten debug statement.
When a selection extends on more than a row, the space between the two
rows should always be painted in full. Otherwise, with layouts like
Chapter, the "Chapter" label may seem selected in part.
With this merge, the way paragraphs are typeset changes. Paragraphs
are first tolenized as row elements, and these elements are then
broken into separate rows as needed to fit the margins. This allows to
reduce the amount of metrics computation and make LyX much faster in
the case of large insets.
Moreover, the code relies more on RofFlags enum, which desribes how an
inset or a row element should be typset. This aspect will be extended
in the future.
Some user for whom performance is very bad (which I cannot reproduce
unfortunately) have reported a 4-fold speedup. In general cases, the
speedup will be less impressive but still noticeable.
Related to bugs #12297 and #5861.
