Mapping Improvements For 4.14

Enhanced CanvasMaps and OutputMaps windows for improved speed and convenience during large-scale events.

Fixes

There are 3 new fixes in this epic.

LA4-6807: Subarea Issue With Negative Size

Selecting and moving a mapped Subarea is offset when the Subarea has a negative dimension (e.g., -360x120 px). The issue occurs in both Canvas maps and Output maps. Repro: create a 100x100 Subarea, map it to Video Output, then resize the mapped Subarea to -100x100. You must click slightly beside the Subarea to select it. Expected: correct hit-testing regardless of negative dimensions.

Status: Done

LA4-6803: Canvas Snapped Resizing

Fixed an issue where resizing a Video Screen (with a texture-mapped Canvas) from the left handle caused a 1 px left shift and unintended narrowing. This appeared as a rounding error but stemmed from snapping behavior. Resizing now preserves accurate position and width.

Status: Done | Requesters: SUP

LA4-6802: Move Video Screen To Canvases

Dragging a Video screen from Objects to Canvases in Canvas Maps causes an application crash. Reproduction: create a Video screen in Canvas, then drag it from Objects to Canvases.

Status: Done

Workspace And Gui Upgrades For 4.14

Enhanced Workspaces for improved usability and functionality.

Improvements

There are 1 new improvements in this epic.

LA4-6791: Workspace Ordering And Navigation

Preserved custom workspace order on project (and LA) reopen. Saved workspaces no longer revert to alphabetical sorting; they remain in the user-defined sequence. Additionally, the navigation arrows in the workspace bar are now context-aware: hidden when all workspaces fit, and shown only when horizontal scrolling is required.

Status: Done

Fixes

There are 2 new fixes in this epic.

LA4-6805: Delete Mapped Canvas

Fixed a crash when deleting a Canvas that was mapped to a Video screen. Previously, creating a Video screen and Canvas, mapping the Canvas to the Video screen, then deleting the mapped Canvas from the Canvases collection caused the app to crash. Deletion now safely handles mapped Canvases without errors.

Status: Done

LA4-6790: Crash When There's No More Previous Workspace

Fixed a crash when triggering Previous workspace from the front (leftmost) workspace via button or Ctrl+PgUp. The action now mirrors Next workspace behavior and wraps from the first to the last (rightmost) workspace.

Status: Done

Other Upgrades

There are 2 new upgrades in this epic.

LA4-6860: First Frame Is Black

Fixed an issue where a black frame briefly appears when the playhead reaches a video layer—most often in Freerun modes.

Status: Done | Requesters: SDS

LA4-6806: Node Pin Disconnect

Fixed a bug where repeatedly dragging from an input pin and dropping on the node could silently break the actual connection while the UI still showed the nodes as linked. The graph now accurately reflects connection state, preventing ghost connections.

Status: Done
