Summary: kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in
glDrawBuffers(unsupported buffer GL_BACK_LEFT)
Classification: Plasma
Product: plasmashell
Version: 6.1.90
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-performance
Assignee: plasma-b...@kde.org

Target Milestone: 1.0
SUMMARY
Sorry, but I don't know if must be kwin or plasmashell...
When I trigger the windows presentation, or when I am triggering the window
switch with alt+tab there a lot of in journal:
kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in glDrawBuffers(unsupported
buffer GL_BACK_LEFT
Lagginess get worse when some other effect is activated while the window switch
is active, things like move the mouse with the "shake-to-find" effect around
the thumbnails or activate the thumbnail hovering the taskbar thumbnail could
hang for a second everything. While this happens, a lot of:
kwin_wayland[1626]: kwin_scene_opengl: 0x1: GL_INVALID_OPERATION in
glDrawBuffers(unsupported buffer GL_BACK_LEFT)
(and kwin_wayland[1626]: kwin_scene_opengl: 0x1: GL_INVALID_VALUE in glScissor
but this is reported in other issue).
and occasionaly it may cause
plasmashell[1854]: kf.windowsystem.wayland: Failed to recreate shadow for
ToolTipDialog(0x6303f3827470)
plasmashell[1854]: qt.qpa.wayland: eglSwapBuffers failed with 0x300d, surface:
0x0
The gldrawbuffers message also happens when working with two screen outputs,
moving the mouse cursor across screens while alt+tab is pressed presents some
lagginess.
I am working with two two output screens like these:
