A paste on Linux and the BSDs read the bitmap on the clipboard worker but waited up to 10 s for it on the UI thread, so a bitmap from an app that never sent its data froze the window long enough for the compositor to offer to close it. The paste now sends the bitmap read to the worker and returns at once; its background thread waits up to 10 s for the answer and converts it to PNG. While that read is open, other reads fail at once instead of queuing behind it. Each read gets its own answer channel, so a late answer is dropped. The check of whether the clipboard still holds the app's own bitmap waits 2 s at most, as text does.
