Coder: blank lines appear when using scroll wheel #71

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Open a .py file with a lot of lines (so that the scrollbar appears).
2. Scroll down using the mouse wheel.

What is the expected output? What do you see instead?
Blank lines appear at regular intervals, obscuring the code (see attached 
screenshot).

What version of the product are you using? On what operating system?
PsychoPy v1.70.00 on Ubuntu 11.04 (Natty).

Please provide any additional information below.
Selecting the text using the mouse or CTRL-A triggers a redraw and the lines 
disappear.

This seems to be a problem with wx and the new windowing environment (Unity) in 
ubuntu. All apps using wx widgets and GTK scrollbars apparently have the same 
issue. Hopefully it will be fixed by either wxPython programmers or by ubuntu 
unity programmers!

PS the link above provides a workaround by changing one of the environment 
variables
PPS issues are now hosted on github, rather than here

Cheers, Jon!

Starting PsychoPy like this fixes the problem (but you get a regular scrollbar 
instead of the fancy Unity one):
LIBOVERLAY_SCROLLBAR=0 /usr/bin/psychopy

I went here because http://www.psychopy.org/links.html links here. Maybe that 
page should link to github instead?
