Subject: ecere/gfx/drivers/OpenGL: Rebinding 0 buffers on making context current
X-Git-Url: https://ecere.com/cgi-bin/gitweb.cgi?p=sdk;a=commitdiff_plain;h=bd7447afc5936833694800beafd49dcbeda22fbe

ecere/gfx/drivers/OpenGL: Rebinding 0 buffers on making context current
- Solved crashes avoiding duplicate bind, when loadGraphics occured, coming back for render and skipping BindBuffer call
- e.g. crashed in Ecere Chess in GLES and SHADERS mode
