--- Comment #76 from Chituc Georgian dianaxxyyzz@gmail.com --- If you run : xwininfo , in terminal , and click on that window , you will see it have a Override Redirect State: yes . If there was a 'no' , the window will be ok . But it has a 'yes' so it preffer to be on top .Linux window manager do not manage this window ,it do not hide it etc , and becase photoshop do not hide it ,itself , that windows stay on top .
