Mouse click-through to element below a dropdown list
Sometimes a dropdown list will cover a slider below it, and clicking the mouse to select an option in the dropdown list will also let that click goes through to the slider, resulted in changing the value of the slider.
One example: in White Balance, select "Direct Sunlight". Clicking on the preset list again will have the top of the dropdown overlapping with the sliders. In this case, clicking "Spot" will also change the "blue" slider to around 7.
Another example: in Base Curve, clicking on the fusion list will have "two exposures" over the "exposure shift" slider beneath it. Thus, clicking "two exposures" will likely change the "exposure shift" to around 3.

Just stock Ubuntu 16.04. Of course it doesn't happen everytime, the click has to line up with the slider below it. I did adjust .config/darktable/darktablerc for font size:

Maybe you can help me troubleshoot this with your knowledge of how DT handles mouse movement and click on DT GUI.
With the G300s mouse, if I click on a dropdown option and keep the mouse button down at the same spot, the slider has not changed yet. The slider will change its value when I release the mouse button (no movement of the cursor).
The mouse's up and down event is normal in Ubuntu's mouse/touchpad testing, double-click works fine. Never had any issue with other applications (Firefox's JS reports single up/down event correctly). Not a button-bounce issue. The mouse is fine with the rest of the system, no mis-click or unintended double-click.
I removed screen_dpi_overwrite option, smaller text, problem still there, so it's probably not related to screen DPI.
This is a gaming mouse with multiple DPI modes. The problem behaves the same for all modes. Perhaps I should just get another mouse for DT :-)
