Gyrth McMulin Posted September 8, 2014 Share Posted September 8, 2014 Hello everyone, So I'm trying out Leadwerks on Linux, since I bought it yesterday. And the animation screen has a bug in it. Parts of the model keep appearing and dissapearing. Causing the screen to flicker. This is running the Steam Leadwerks version without any beta opt ins. Here are my pc specifications. Antergos (Arch Linux) Linux 3.16.1-1-ARCH Intel® Core™2 Quad CPU Q9550 @ 2.83GHz GeForce GTX 660 Ti/PCIe/SSE2 Nvidia 340.32 Driver I hope this is enough information. I'd be happy to provide more to help Leadwerks become even better. [media] [/media] Regards, Gyrth. Link to comment Share on other sites More sharing options...
DerRidda Posted September 8, 2014 Share Posted September 8, 2014 This is a know issue afaik, but I just want to remind people that this also happens on Ubuntu before this gets dismissed as a non-Ubuntu bug report. Link to comment Share on other sites More sharing options...
Josh Posted September 8, 2014 Share Posted September 8, 2014 It's an Nvidia driver bug. My job is to make tools you love, with the features you want, and performance you can't live without. Link to comment Share on other sites More sharing options...
DerRidda Posted September 8, 2014 Share Posted September 8, 2014 I think it's the same bug that makes Firefox flicker in an epilepsy inducing way. The question I have is: Why does it just happen in the model viewer and not the 3D viewport or the game engine? Link to comment Share on other sites More sharing options...
Gyrth McMulin Posted September 9, 2014 Author Share Posted September 9, 2014 I tried it with the NVidia 343.13 beta drivers and got this message: "Failed to initialize graphics. Please ensure your graphics hardware is compatible and install new graphics drivers." Link to comment Share on other sites More sharing options...
Gyrth McMulin Posted September 9, 2014 Author Share Posted September 9, 2014 The Nvidia 304.123 legacy drivers seem to have the same flickering bug. Link to comment Share on other sites More sharing options...

cocopino Posted October 2, 2014 Share Posted October 2, 2014 I am seeing the exact same issue in LE 2.50. I've tried 3 separate Windows systems having 3 different videocards, but it doesn't seem to matter. "Groups" inside an animated model are switching on and off. It must be a relatively new issue though, models that were always fine now have this problem in the 2.5 modelviewer. Oddly, when loading the same model inside a (Blitzmax) program and then using a debug build instead of release, it does not happen. Also, when not animating, the flickering stops (the group stays either visible or invisible). Hope this helps. desktop: Quad core Q6600 + 4GB + ATI HD4890 + XP laptop: Dual core T6400 + 4 GB + NVidia 9600M GT + Vista 32 Link to comment Share on other sites More sharing options...
Josh Posted October 3, 2014 Share Posted October 3, 2014 I ordered two new GPUs and they should arrive early next week.

DerRidda Posted November 14, 2014 Share Posted November 14, 2014 This still happens with Nvidia's latest beta drivers that has some fixes concerning corrupted rendering. Fixed rendering corruption that sometimes happened when calling DrawElementsInstancedBaseVertexBaseInstance(), DrawElementsInstancedBaseInstance(), or DrawArraysInstancedBaseInstance() So if you thought the driver bug was related to these it apparently isn't.

Guppy Posted November 15, 2014 Share Posted November 15, 2014 still happening on AMD aswell System: Linux Mint 17 ( = Ubuntu 14.04 with cinnamon desktop ) Ubuntu 14.04, AMD HD 6850, i5 2500k Link to comment Share on other sites More sharing options...
DerRidda Posted January 20, 2015 Share Posted January 20, 2015 As far as I can tell, the latest stable Nvidia driver has eliminated all similar remaining corruption issues in other games and applications except Leadwerks. http://www.geforce.com/drivers/results/81252 This issue deserves more attention because the model viewer is essentially useless on Linux this way as 90% of the model seems to be invisible at any given time.

DerRidda Posted February 18, 2015 Share Posted February 18, 2015 Ever tried if creating a non-shared context just for the model editor would be a good workaround/solution? Link to comment Share on other sites More sharing options...
Josh Posted February 18, 2015 Share Posted February 18, 2015 No, that would cause a lot of new problems. My job is to make tools you love, with the features you want, and performance you can't live without. Link to comment Share on other sites More sharing options...
DerRidda Posted February 18, 2015 Share Posted February 18, 2015 I did some (fairly superficial) reading in regards to OpenGL context sharing so I don't know how helpful this is but it seems that in GLX you might have to share explicitly before the context is active for the first time. Is there any kind of "sloppiness" in the code that's in there because it works Windows and you didn't expect different behavior with GLX? I'm asking around, I have access to a few porters and devs that might know what could cause this behavior. Link to comment Share on other sites More sharing options...
Josh Posted February 19, 2015 Share Posted February 19, 2015 Nvidia is the most likely entity to be able to answer this. Trying to make non-shared contexts would be a real mess. I don't even know if that is the cause, I just speculated that because I didn't know what else it could be.

codeape Posted February 19, 2015 Share Posted February 19, 2015 Another video on the subject this time with voice added to hopefully get the point across that this bug is not Nvidia specific. I do not know if this helps, but it looks like AMD is having problems with flickering all over the place: https://www.google.se/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=radeon+hd+6850+linux+catalyst+driver+flickering+site:forums.amd.com I found some Linux Catalyst 13 dirvers in the mix and various cards including 6850 so do you see this problem in other OpenGL apps?
