Aliaksandr Kalenik	6507d23e29	LibWeb: Save ScrollState snapshot in DisplayList to avoid race condition ... With this change we save a copy of of scroll state at the time of recording a display list, instead of actual ScrollState pointer that could be modifed by the main thread while display list is beings rasterized on the rendering thread, which leads to a frame painted with inconsistent scroll state.

Aliaksandr Kalenik	12a2aebeb6	LibWeb: Move painting surface allocation into rendering thread ... Skia has a check in debug mode to verify that surface is only used within one thread. Before this change we were violating this by allocating surfaces on the main thread while using and destructing them on the rendering thread.	2025-04-03 22:01:43 +02:00

Aliaksandr Kalenik	24e2c402f5	LibWeb+WebContent: Move display list rasterization off the main thread ... The display list is an immutable data structure, so once it's created, rasterization can be moved to a separate thread. This allows more room for performing other tasks between processing HTML rendering tasks. This change makes PaintingSurface, ImmutableBitmap, and GlyphRun atomic ref-counted, as they are shared between the main and rendering threads by being included in the display list.	2025-03-31 15:58:15 +01:00
