Can you retest with current master?

[karroffel]

possibly related to #8105

[Ahmed0425]

@karroffel Exactly
@bojidar-bg Tested and didn't work

Are you opening a previously created scenes with 3D meshes? I found my similar GL errors went away after creating a new project.

[Ahmed0425]

@jedStevens No ... I open a blank project

Experiencing the same on Windows 8.1

ERROR: There are still MemoryPool allocs in use at exit!
At: core/dvector.cpp:68

At line 68 instead of 71 though

EDIT
Just a little funny side node, and possible workaround.

This is how godot looks when starting a project and those errors appear.
If the "maximize" icon is clicked so the godot window goes away from fullscren, godot appears again and works.

A long time has passed since, so assuming fixed in 3.0 beta 2 or later. Please comment if you still reproduce the exact same errors.

[Ahmed0425]

No, I do not reproduce this anymore
