I have an unfortunate problem. I’ve recently started distributing my game built in java + opengl and it works fine on the handful of graphics vendors I’ve tested it on. Only the ones that are on a nvidia gtx 1080 are experiencing problems. And the problem is an out of memory from polling glerrors. …

I can confirm that using a second FBO with the same dimensions as the default FB and a blit fixed the original bug. It’s unclear how/if this caused the OUT_OF_MEMORY. Could be the client was actually low on memory when trying it out the first time, could be change in drivers, or could be some of the…

Thanks a lot. Got much to consider now. I’ll definitely monitor memory consumption on my own machine. It might give me some clues. And I’m sorry I didn’t provide enough information. Just to clarify: I’ve personally tested this on GTX 960, GTX 1050 and Intel(R) UHD Graphics 630. This with debug outp…

[image] jaketehsnake: I’ve personally tested this on GTX 960, GTX 1050 and Intel(R) UHD Graphics 630. This with debug output on and there are no warnings/errors. I’ve monitored GPU memory usage with gpu-z and memory usage is consistent on those cards. Additionally, roughly 20 random gamers hav…

Thanks again Dark Photon! I didn’t realize there were several versions of 1080. From what I gather, the user is running windows on 32-bits? (For whatever reason) ---Running on a: Windows 10, x86 Platform. I’ve also set maximum heap to 1GB. The game itself never uses more that 200MB. —JRE Input A…

[image] jaketehsnake: Also, texture creation does not return any errors. … The constructor _TextureNormal creates a texture. Just basic texture creation. It does perform a glGetError() after that doesn’t return anything. So, at this ponit everything is fine. … `glFramebufferTexture2D(GL_DRAW…

[image] Dark_Photon: This is one reason why it’s common to pre-render with textures prior to hitting your main game loop. It’s sometimes called “texture warming”. In practice I am doing that I think. The texture is a sprite atlas, the only texture used throughout the game. Prior to hitting my…

[image] jaketehsnake: I came across this from the documentation : I am reading and writing to the same pixels. I can live with undefined results, but could this “feedback loop” consume memory somehow? Well theoretically, undefined includes memory consumption. But practically, I doubt it. S…

Ok then. I might not understand the terminology sufficiently, but my entire rendering pipeline basically first writes to textures, then reads from those textures and writes to others until the last one is blit to the screen buffer, so if I’d ever truly ever experience undefined pixels, I’m screwed. …

Ok, I’ve manged to interact with the person with the bug and made another build for him riddled with opengl error checks. Initiation seems fine, however, it now crashes at the first swap buffer.

[image] jaketehsnake: Message: GL_INVALID_OPERATION error generated. Source and destination dimensions must be identical with the current filtering modes. …I have a sneaking suspicion that it’s generated when I blit my FBO to the system FB at the end of my rendering loop. glBindFramebuffer…
