Hello guys, first of all, let me say one big thank you for all of your efforts to make music software work on linux. I'm in process of evaluating TL GFX and Jam products on OpenSUSE linux and faced an issue trying to access main menu in Jam. Whenever I try to open any of main menu options with mouse, Jam crashes showing 'Critical error in application' dialog. I've mailed a report it generates. I've reproduced it under gdb: and generated coredump file. It size ~1.2GB uncompressed, and ~54MB when compressed with 7z. Please let me know where to upload it should you need it. Looks like an issue, which was fixed recently, and described here: https://tonelib.net/forums/threads/tonelib-jam-3-9-9-crashing-on-linux.5975/ But that issue was fixed, and version of Jam I'm using is 4.3.4 (current at the moment). I'm using OpenSUSE Leap 15.0 x86_64, nothing special. Could you, please, give some advise on how to resolve or overcome this issue. Any additional information - on your request. There are a couple more issues which are not so significant, but if you please: 1. After mentioned crash, trying to start Jam results in absence of main window, only Quick Start dialog is visible for some seconds, after that Jam closes completely. There is message in console related to this case: After some runs, this issue disappears - Jam starts normally. 2. During mentioned crash, if I agree to send an error report, it doesn't actually send it, instead I see in console: So, I've decoded that message and sent it manually. I will be glad if this information will help to make the products more reliable. P.S. Updated my initial post a bit.
