In RAP 3.5 we introduce a change (https://git.eclipse.org/r/#/c/121339/) to fix the order of drawing images. It seems that this change cause your problem. Is it possible for you to create a simple entry point to reproduce the crash?

New Gerrit change created: https://git.eclipse.org/r/126885

Comment 3 Ivan Furnadjiev

Victor, please give the above change a try. Does it fix your issue?

Comment 4 Victor Kirhenshtein

2018-08-01 07:20:44 EDT

Looks like this change fixed the crash. View that was causing almost immediate crash works stable now.

Comment 5 Ivan Furnadjiev

2018-08-01 07:58:51 EDT

Perfect!
