description |
I just noticed client-provided alpha is not being blended correctly and mir_demo_client_multiwin looks significantly different now to how it always did up to around June. The resulting colours are additive (brighter) when clients with alpha overlap each other.
Test case: Run mir_demo_client_multiwin
Expected: Areas of overlap should be darker than non-overlapping areas
Observed: Areas of overlap are at least as bright as non-overlapping areas. |
I just noticed client-provided alpha is not being blended correctly and mir_demo_client_multiwin looks significantly different now to how it always did up to around June. The resulting colours are additive (brighter) when clients with alpha overlap each other.
Test case: Run mir_demo_client_multiwin in mir_demo_server_shell
Expected: The pure red/green/blue regions should be darkened by their high transparency and the grey background behind them.
Observed: The pure red/green/blue regions are full brightness, despite having opacity of only 0x50 (0.31f) in front of a grey background. |
