Highlight disappears when using mouse drag scroll with right key

<< < (3/4) > >>

BlueHazzard:
i try to look into it. Things i can say so far:
1) The problem is that the selection gets reseted after pressing the right mouse button.
1.1) Normal would be to reset the selection after the release of the mouse button
2) This does not happen before the scintilla update as OP posted the failing revision
3) The wxWidgets 3.0.4 STC sample does not show this behavior --> The selection is not cleared after clicking the right mouse button
4) The selection is not cleared if the right click occurs on top of the selection and the context menu pops open...

i don't know where to search... is this a miss fired event?
I have no contrib plugins activated (only mouse drag and the provided plugins)

oBFusCATed:
Probably put a breakpoint in the scintilla calls which handle selections and see why are they called on right-down instead of right-up/press.

BlueHazzard:
some small update
i can observe that in the old version a wxEVT_SCI_MODIFIED event is fired on the right button release, on the new version on the right button press...

oBFusCATed:
I don't see a modified event posted on right click (on linux).
Can you post the full callstack? What is happening in the modified handler?

BlueHazzard:
not quite sure if this is the culprit...
