Bug #: 42131 Summary: Problem with resizing OpenGL windows when using XCB Classification: Unclassified Product: Mesa Version: 7.11 Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: nilschrbrause@googlemail.com
Created attachment 52651 --> https://bugs.freedesktop.org/attachment.cgi?id=52651 Test program demonstrating the problem
The attached program creates a window using XCB and draws a rectangle inside it using OpenGL. When using indirect software rendering (LIBGL_ALWAYS_INDIRECT=1), everything works as expected. But when using the R600 Gallium3D driver, the OpenGL view port doesn't seem to get resized properly and the window contents get screwed up.
