Description
This hrev53937.
When running NetPositive with https://review.haiku-os.org/c/haiku/+/2284 applied (it have better comatibility with BeOS applications), and opening context menu, it is not possible to close context menu anymore. After adding debug output I found that BView::GetMouse
is returning wrong values when checkMessageQueue
is used. In some cases values are not updated at all. When setting checkMessageQueue
to false
in beginning of BView::GetMouse
, context menu of NetPositive start to work properly.

This problem also seems to cause Pe freeze sometimes.

This bug is also causing Pe freeze sometimes. Pe use polling loops with GetMouse
, for example PText.cpp:2113 and that loops are never exit sometimes because GetMouse
stop updating values and never return all mouse buttons released.

This bug start to getting annoying when working on RISC-V port. It require to terminate Pe when it freeze in GetMouse()
loop, causing closing all windows and possible loss of changes.
We have changed the way pointer history works in Haiku, views need to specify B_FULL_POINTER_HISTORY if they want that. In BeOS this was the default and views needed to specify B_NO_POINTER_HISTORY if they did want the OS to merge mouse events together. This is possibly related.
