Problem: When 'hlsearch' is set and matching with the last search pattern
is very slow, Vim becomes unusable. Cannot quit search by
pressing CTRL-C.
Solution: When the search times out set a flag and don't try again. Check
for timeout and CTRL-C in NFA loop that adds states.
Problem: If a job writes to a buffer and the user is typing a command, the
screen isn't updated. When a message is displayed the changed
buffer may cause it to be cleared. (Ramel Eshed)
Solution: Update the screen and then the command line if the screen didn't
scroll. Avoid inserting screen lines, as it clears any message.
Update the status line when the buffer changed.
Problem: Using a function pointer instead of the actual function, which we
know.
Solution: Change mb_ functions to utf_ functions when already checked for
Unicode. (Dominique Pelle, closes#1582)
Problem: Storing a zero byte from a multi-byte character causes fold text
to show up wrong.
Solution: Avoid putting zero in ScreenLines. (Christian Brabandt,
closes#1567)
Problem: Tabs are not aligned when scrolling horizontally and a Tab doesn't
fit. (Axel Bender)
Solution: Handle a Tab as a not fitting character. (Christian Brabandt)
Also fix that ":redraw" does not scroll horizontally to show the
cursor. And fix the test that depended on the old behavior.
Problem: With 'linebreak' set and 'breakat' includes ">" a double-wide
character results in "<<" displayed.
Solution: Check for the character not to be replaced. (Ozaki Kiichi,
closes#1456)
Problem: If [RO] in the status line is translated to a longer string, it is
trunctted to 4 bytes.
Solution: Skip over the resulting string. (Jente Hidskes, closes#1499)
Problem: If a wide character doesn't fit at the end of the screen line, and
the line doesn't fit on the screen, then the cursor position may
be wrong. (anliting)
Solution: Don't skip over wide character. (Christian Brabandt, closes#1408)
Problem: When concealing is active and the screen is resized in the GUI it
is not immediately redrawn.
Solution: Use update_prepare() and update_finish() from
update_single_line().
Problem: When update_single_line() is called recursively, or another screen
update happens while it is busy, errors may occur.
Solution: Check and update updating_screen. (Christian Brabandt)
Problem: Using a NULL pointer when using feedkeys() to trigger drawing a
tabline.
Solution: Skip drawing a tabline if TabPageIdxs is NULL. (Dominique Pelle)
Also fix recursing into getcmdline() from the cmd window.
Problem: Display problem with 'foldcolumn' and a wide character.
(esiegerman)
Solution: Don't use "extra" but an allocated buffer. (Christian Brabandt,
closes#1310)
Problem: Test_help_complete sometimes fails in MS-Windows console.
Solution: Use getcompletion() instead of feedkeys() and command line
completion. (Hirohito Higashi)
Problem: When a match ends in part of concealed text highlighting, it might
mess up concealing by resetting prev_syntax_id.
Solution: Do not reset prev_syntax_id and add a test to verify. (Christian
Brabandt, closes#1092)
Problem: In the GUI when redrawing the cursor it may be on the second half
of a double byte character.
Solution: Correct the cursor column. (Yasuhiro Matsumoto)
Problem: Using 'hlsearch' highlighting instead of matchpos if there is no
search match.
Solution: Pass NULL as last item to next_search_hl() when searching for
'hlsearch' match. (Shane Harper, closes#1013)
Problem: Warning for assigning negative value to unsigned. (Danek Duvall)
Solution: Make cterm_normal_fg_gui_color and _bg_ guicolor_T, cast to long_u
only when an unsigned is needed.
Problem: When using matchaddpos() a character after the end of the line can
be highlighted.
Solution: Only highlight existing characters. (Hirohito Higashi)
Problem: In the GUI the cursor is hidden when redrawing any window,
causing flicker.
Solution: Only undraw the cursor when updating the window it's in.
Problem: Setting 'display' to "lastline" is a drastic change, while
omitting it results in lots of "@" lines.
Solution: Add "truncate" to show "@@@" for a truncated line.
Problem: The cursor blinking stops or is irregular when receiving date over
a channel and writing it in a buffer, and when updating the status
line. (Ramel Eshed)
Solution: Make it a bit better by flushing GUI output. Don't redraw the
cursor after updating the screen if the blink state is off.
Problem: Still cursor flickering when a callback updates the screen. (David
Samvelyan)
Solution: Put the cursor in the right position after updating the screen.
Problem: GUI: cursor drawn in wrong place if a timer callback causes a
screen update. (David Samvelyan)
Solution: Also redraw the cursor when it's blinking and on.
