What's fixed
- Your shortcuts in the stream menu work in games again: a tile now holds its keys for a moment, so the Steam overlay (Shift + Tab) and games that read keys once a frame see them. Same on Windows and Linux.
- Disconnect and Quit no longer freeze or crash the app when the decoder is restarting at that moment, for example after an HDR change.
Tested. On a Retroid Pocket against a Rubylight test host, a Shift + F9 shortcut tile held F9 for 99 ms at the PC, where 4.3.0 held it for 0.3 ms. Twenty Disconnect, End session and Quit game cycles at AV1 120 fps gave no freezes, with Disconnect taking 8 to 15 ms. A unit test reproduces the freeze during a decoder restart and passes with the fix. The Android unit suite (4167 tests) and the desktop client's Rust tests pass.
