My plateform is Ubuntu LTS with Nvidia proprietary driver I noticed the bug come and go when update my system (Lately, it comes back when updating to 18.04 with nvidia-390)
I write out adresses, they indeed differs: Code: glGetTextureHandleARB:0x7ffff2d8c4a0 glIsTextureHandleResidentARB:0x7ffff2d8e1e0 glMakeTextureHandleResidentARB:0x7ffff2d8ea40 glGetTextureHandle:0x7fffe2f622e0 glIsTextureHandleResident:0x7fffe2f62360 glMakeTextureHandleResident:0x7fffe2f62320 If you know a proper way to contact nvdia driver support for linux...
