Here's proc adresses:

glGetTextureHandleARB:0x7ffff2d8c4a0
glIsTextureHandleResidentARB:0x7ffff2d8e1e0
glMakeTextureHandleResidentARB:0x7ffff2d8ea40

glGetTextureHandle:0x7fffe2f622e0
glIsTextureHandleResident:0x7fffe2f62360
glMakeTextureHandleResident:0x7fffe2f62320

And as you can see it differs

Objet : 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 :/
Cheers

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:

https://openbenchmarking.org/result/1808254-KH-TRY2REPRO45
<https://openbenchmarking.org/result/1808254-KH-TRY2REPRO45>

Try2repro Benchmarks [1808254-KH-TRY2REPRO45] - OpenBenchmarking.org<https://openbenchmarking.org/result/1808254-KH-TRY2REPRO45>
openbenchmarking.org
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)


Cheers
