Re: GL_ARB_bindless_texture didn't work anymore after upgrading Ubuntu to 18.04 4.15.0-33-generic
Ok I found the problem:
getting proc address with no ARB suffix (ex:glGetTextureHandle) return not working funcs
I added ARB suffix (glGetTextureHandleARB) and all work fine
It's strange ...it was working before :/

Objet : GL_ARB_bindless_texture didn't work anymore after upgrading Ubuntu to 18.04 4.15.0-33-generic
After upgrading to Bionic Beaver my programs have problems with GL_ARB_bindless_texture:
I reproduced this bug with an example provided by OpenSceneGraph project (example osgbindlesstext)
I debugged what I can but all seams right. Altough all calls to texture2D in glsl gives 0.
I ran benchmarks but none include the feature:
Try2repro Benchmarks [1808254-KH-TRY2REPRO45] - OpenBenchmarking.org<https://openbenchmarking.org/result/1808254-KH-TRY2REPRO45>
Benchmarks of try2repro with Linux test results, hardware information, and performance data.
Here it is. At least for my complete system spec...:/
It's no the first time this feature break after driver update so perhaps it's in Nvidia hands ..but If I can help to fix it I would be glad...
.perhaps in creating a specialize beanchmark for this feature or something
(Render to texture bind less stuff, readback and fails if image is black)
