[REG: 5.11.3->5.12.5] Flickering when alpha channel is requested, but there is no such visual

XMLWordPrintable

    • Linux/X11

      To reproduce, set XLIB_SKIP_ARGB_VISUALS=1 environment variable and run attached example.

      The environment variable makes sure there are no argb visuals. However the application tries to set alpha channel, which probably should just fail and use some other visual, but for some reason this also causes it to flicker.
