Description lro27292 2021-02-14 14:59:45 UTC 
SUMMARY
Splits with background blur either flicker or stop being blurred.

STEPS TO REPRODUCE
1. Create at least two profiles, one with background blur, one without
2. Create a split
3. Set one split to the blurred profile, the second split to the solid-background profile
4. Select the split without a blurred background

OBSERVED RESULT
The split with the blurred background profile either flickers between crisp and blurry, or stays crisp

EXPECTED RESULT
The split with the blurred background profile should blur the background

I assume this is the same bug as Bug 456052

Konsole probably needs to specify the region parameter in:
KWindowEffects::enableBlurBehind(QWindow *window, bool enable = true, const QRegion &region = QRegion())
