           Summary: First icon in icons-only task manager is distorted
                    when using window rules
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux

  Target Milestone: ---

SUMMARY
If I have some application which would usually cause kwin to disable
compositing, but I have this app configured with window and app rules to not
block compositing, the first icon in the icons-only task manager will look
distorted (see picture).

STEPS TO REPRODUCE
1. Launch some app that would usually block compositing (such as tauon music
player), but set window and app rules for it to not block compositing. Perhaps
restart the app if necessary for these rules to kick in.
2. Start launching apps so that the icons-only task manager gets more icons
until it needs to shrink them.
3. Watch the first icon in the task manager.

OBSERVED RESULT
Icon is distorted (only the first one, rest are Ok).

EXPECTED RESULT
Icon should render normally.
