[BUG] Transparent windows have shadow bleed #62

Closed n4n0GH closed 4 years ago

n4n0GH commented 4 years ago

Describe the bug The update a7d186ef introduced a bug with transparent windows which now exhibit a weird "bleed" of the shadow. This was discovered by @arun54321 here: https://github.com/n4n0GH/hello/commit/a7d186efc8acf340c36851fc244634fa626f46db#commitcomment-36760619

To Reproduce

  1. Using transparency on any window should show the result

Expected behavior The shadow should not bleed back into the frame, even if it's transparent.

Bug inheritance N/A

Additional context The update included a change in how the alpha blending is calculated, I suspect that to be the cause.

Closing this as I most likely won't be working on this any further (see 5f57998e).
