Hi all,

I just tried the r6983 master build on Windows 10 and my log gets spammed with thousands of entries like this:
Warning [Main]: QWindowsEGLContext::swapBuffers: Failed to swap buffers. eglError: 12301, this: 0x235a5cd4790

OpenGL Status in the Waveform panel of the settings reads "ES 2.0 (ANGLE(Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1))
It's an older Sony Vaio Laptop. 2.2.2 runs nicely on it, so I guess this related to the recent switch in the GL implementation. Would be nice to get the new version running as well, for now I'll have to stick with the release version.

As I suppose I'm not the only one with an older Intel HD, I thought I'd let you know. If you need more info, please feel free to ask.

OS: Windows 10, 1903
CPU: Intel Pentium 987 1.5 GHz
GPU: Intel HD Graphics
Log attached.

Cheers,
René

Hi guys,

I just had another go with the latest master build and noticed, that this might be a dplicate of

Using QT_OPENGL=desktop it apparently works fine.
Best,
René
