When the `List` element's state is `ListState::reset()`, it eagerly
trashes it's cached element heights in anticipation of a prompt render.
But, due to the recent `display_layer` changes, that re-render is not
always forthcoming. This is a problem for `ListState::scroll()`, which
depends on these cached elements to correctly calculate the new logical
scroll offset.
Solutions we attempted:
- Cache the element heights and continue the scroll calculation
- This was conceptually incorrect, reset should only be called when the
underlying data has been changed, making any calculation with the old
results meaningless.
- Lazily re-compute the element heights in scroll
- Beyond being a non-trivial refactor, this would probably also cause us
to double-render the list in a single frame, which is bad.
- Cache the scroll offset and only calculate it in paint
- This solution felt awkward to implement and meant we can't supply
synchronous list scroll events.
- Delay resetting until paint
- This means that all of the other APIs that `ListState` supplies would
give temporarily incorrect results, worsening the problem
Given these issues, we settled on the solution with the least
compromises: drop scroll events if the state has been `reset()` between
`paint()` and `scroll()`. This shifts the responsibility for the problem
out of the List element and into consumers of `List`, if you want
perfectly smooth scrolling then you need to use `reset()` judiciously
and prefer `splice()`.
That said, I tested this by aggressively scrolling the Collab panel, and
it seems to work as well as it did before.
This PR also includes some initial testing infrastructure for working
with input from the platform and rendered elements.
Release Notes:
- N/A
Before this change we wouldn't submit all possible primitives of the
same kind that are less-than the max order.
Result was that we would submit, say, 10 paths each in a separate batch
instead of actually batching them.
This was overly strict because even if the order of two different
primitives was the same, we could have still batched the 1st primitive
kind, if its implicit ordering was less than 2nd kind.
Example: say we have the following primitives and these orders
5x paths, order 3
2x sprites, order 3
Previously, we would submit 1 path, 1 path, 1 path, 1 path, 1 path, then
the sprites.
With this changes, we batch the 5 paths into one batch.

Previously, we were using `size_of` but passing the wrong type in
(MonochromeSprite instead of PathSprite). This caused us to read outside
of the `sprites` smallvec and triggered the segfault.
We're occasionally seeing a crash in MetalRenderer::draw.
Looking at the backtrace, it seems almost certainly to be happening in
the call to `ptr::copy_nonoverlapping` on line 604 (see `#Don't Panic!`
channel notes)
As we already have added bounds checking to the destination, it seems
most
likely (however improbable) that somehow we're getting an invalid Ptr
and
length from the SmallVec.
To try and make progress on this, let's try a Vec for a bit lest there
is a subtle issue in SmallVec (though I couldn't spot one).
Release Notes:
- (maybe) Fixes SEGFAULT in MetalRenderer::draw
According to Chromium source, `NSScreen::screens` should always get us
one display.
We made this change because we ran into panics caused by the previous
`unwrap()` when `CGGetActiveDisplayList` might return an empty list.
Previously we called CGGetActiveDisplayList twice: once to get the
number of displays and then to get the displays.
We saw a panic due to no displays being returned here. As a first
attempt to fix the panic, we're reducing the amount of calls to
CGGetActiveDisplayList and just do one with the trade-off being that we
pre-allocate 32 pointers in a Vec.
Now that views are cached, we need to explicitly `.notify()` text
editors when the buffer font size changes.
* [x] Notify editors when settings change, or adjusting buffer font size
* [x] Figure out why non-focused editors still do not re-render when
adjusting buffer font size
* [x] Reset buffer font size adjustment when the size is updated in the
user's settings
- Update chat panel with current channel
- Open chat panel for guests
- Open chat when joining a channel with guests
- Some tweaks for chat panels
- Don't lose focus on default panel state
- Make chat prettier (to my eyes at least)
- Fix multiple mentions in one message
- Show a border when scrolled in chat
- Fix re-docking chat panel
- Move settings subscription to dock
[[PR Description]]
Release Notes:
- Opens chat by default when joining a public channel
- Improves chat panel UI
Ensure we `panic()` instead of crash on graphics memory buffer overflow
Also bump the buffer size to 32Mb from 8Mb to make this rarer (but still
possible)
Release Notes: Fixes some crahes due to lack of graphics buffer spacae
During layout of EditorElement we use 'm' character from current font to calculate sizes, panicking with fonts that do not have that character (e.g. Arabic fonts). It's not really EditorElement's fault, as it assumes that the font it's dealing with is gonna have that character available.
To prevent a crash, I added validation while loading a family that a given font contains the glyphs we're gonna use down the line.
