openBrain 2020-06-04 18:10 developer ~0014460	@ljkenny : please address your issue following our reporting guidelines by opening first a topic in our forum. Thx We generally accept tickets when issue has been vet by the community, and especially confirmed to still exist in current development version (which you can test by yourself).

ljkenny 2020-06-05 05:59 reporter ~0014463	Thanks for getting back to me. Unfortunately, time is too valuable to chat on forums. I'll use something else instead. Feel free to either close-out this report, or wait for potential "me too"s.

I'll use something else instead. @ljkenny you may be surprised to learn that in all probability you'll have a a more valuable experience if you communicate with the community via the forum Can you recreate on 0.19.x ? Try the AppImage to see if you can reproduce. Note: you can run different versions of FC in parallel (just save your 0.18.x files before opening them in 0.19.x)

openBrain 2020-06-05 12:35 developer ~0014467	@ljkenny : are you suggesting your time is more valued than our, so that you don't have to follow the guidelines we set up in order to get an efficient bug fixing issue ? You can use something else but your problem will persist anyway. This isn't a FreeCAD issue but an incompatibility between OpenGL and your GFX system. You'll have the same problem as soon as trying to run an application using OpenGL (and there are many). You could have found by yourself very easily that this problem is actually an issue of your system (https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1877879). But I guess your time it too valuable to have a quick check on the internet...
