Chimera X QT bug?

[hernando.sosa@…]

Here is an example of the behavior. To activate and select the "Show molecular surface" the cursor has to be placed  between the red arrows. Higher up where the corresponding icon is does not work.  The same happens with all the other icons and regardless if the ChimeraX widows is resized (but see below)

However I just found out that if  I set the laptop to use the Geforce graphic card for 3D rendering the mouse mapping is OK. i.e.  mouse pointer  on top of the icons work as expected.

Alternate settings that work:
UCSF ChimeraX version: 0.1 (2017-08-15)
OpenGL version: 3.3.0 NVIDIA 382.05
OpenGL renderer: GeForce GTX 960M/PCIe/SSE2
OpenGL vendor: NVIDIA Corporation

Therefore the problem seems related to using the intel CPU OpenGL for display

Hi Hernando,

This seems like a Qt window toolkit bug.  We do not observe this on Windows 10 or any other operating system, although reports on the web suggest Qt can sometimes get confused about the window position if you minimize or maximize the window.  Does it fix itself if you manually resize the ChimeraX window or move the window?  You can send email to chimerax-bugs@cgl.ucsf.edu<mailto:chimerax-bugs@cgl.ucsf.edu> to make a bug report.  It will be hard for us to do anything about it if we cannot make it happen on one of our machines.

Hi Elaine,

I figured it out what the problem may be. For some reason the mouse position it is not mapped out correctly in the ChimeraX window. I.e. the icons are active but the cursor has to be placed not on top of the icon but somewhere else close by (below).  This occurs  with the latest daily build or the latest alpha version. I am running it in a Windows 10 laptop.

This problem only appears with Intel graphics, not with Nvidia graphics using the same machine. So it looks like a problem with the Intel graphics driver.
