U++ Drawing/Positioning Issue with Linux Mint Mate + Compiz
https://www.ultimatepp.org/forums/index.php?t=rview&goto=43917&th=9115#msg_43917
Test System: OS: Linux Mint 17 Mate Desktop Windows Manager: Compiz ("compiz" source package in Trusty, Version 1:0.9.11.2+14.04.20140714-0ubuntu1 uploaded on 2014-07-14) Display Driver: Linux Kernel's built in driver. Hardware Specs: dont think its related to hardware. is it?
Precursor:
At startup of desktop, I use compiz (OpenGL compositing window manager) to replace the regular mdm(Mdm display manager) that comes by default with Linux Mint as windows manager. Compiz is fast and fancy desktop/windows manager. However I just found that U++ seems to have some strange issues drawing and interacting with mouse position when Compiz use as windows manager.
Issue:
if a window drawn by U++ is moved in runtime then mouse positions is not updated and u++ still uses the old(expired) window position to draw or to take actions ie (mouse click left/right etc). please see the picture attached. in this picture, I moved theIDE window and then click the "File" menu. the "File" menu is drawn at the old windows location. This issue also manifest in other more severe ways that render GUI almost unusable. If one opens theIDE > Setup > Environment dialog and then moves it around, than most of the check-box refuses to take any mouse input(clicks). I believe this two problems are actually related, and somehow on window move, upp is not getting the new locations of the top window and in turn all child window objects causing it to draw in invalid locations and also trying to receive mouse input from wrong pixel locations.
this problem is not limited to only theIDE, rather applies to any program written in U++ GUI. I have tested other application written in U++ suffers from same issue.

Can you write more information about your Upp distribution (version, backend (X11 or GTK))?

Can you compile any applications with flag "X11" and check if this bug is there? Maybe it is fixed due to default backend change (Now GTK is default), but bug still may be in X11 core.
* Flag description:
X11 - X11 with gtk theming
NOGTK - pure X11 without gtk theming
