Several testers have reported problems with vector chart objects disappearing in certain screen
OpenCPN for Android Beta test 4.1.530
We had this trouble earlier on chart outlines fading away in certain screen
sections. This was fixed in 705, I understand....
But there is still some problem.
I am trying to track this down and fix it for good. Here is what I know:
1. Seems to affect only some devices, particular to the OpenGL drivers onboard, I think. Unfortunately, it affects none of my devices, nor does it show up on any emulators.
2. I think it becomes a factor when certain types of symbols are rendered. Buoys, and other raster cached images
are OK. But I think pen-drawn objects like lighthouses are affected when they are in certain areas of the screen. Sometimes drawn area boundaries, as well. And light sector extensions.
So, a little help, please.
Those who are seeing this, I need some screen shots with the above in mind. A/B comparisons of dense vector charts
(cm93 OK). Find a spot that has a some drawn objects and some raster objects. Pan around, looking for features that disappear in certain screen regions as you pan
When you pan slowly, do they wink out, or do they fade out? Any example pix would be useful.
Please include your logfile OpenGL entry section, if possible. I think we can narrow this down to certain GL drivers...
This may be a wild goose chase, but there is something fishy here...
