            Bug ID: 417745
           Summary: Relatively high CPU usage when attempting to
                    copy/paste a file with an existing name.
           Product: dolphin
           Version: unspecified

A small video showing high CPU usage even though copying hasn't started

SUMMARY
Animations in the task bar and notification window seem to incur high CPU usage
even though copying hasn't been initiated.

STEPS TO REPRODUCE
1. Open the System Monitor.
2. Open a folder in Dolphin. Select a file. Press Control+C.
3. Then press Control+V.

OBSERVED RESULT
A dialogue window appears 
• informing the user that the file already exists and
• asking for another filename
At the same time even though a new name hasn't yet been suggested,
• a slider indicating copying progress appears and
• an animation appears in the panel
• System monitor shows high CPU usage which continues until the Cancel button
is pressed or a new name is suggested and the Continue button is pressed.

EXPECTED RESULT
The slider indicating copying progress and the animation in the panel should
appear only **after** a suitable alternative name is provided and the Continue
button is clicked.

SOFTWARE/OS VERSIONS

Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.0
KDE Frameworks Version: 5.67.0
Qt Version: 5.12.5
Kernel Version: 5.4.0-14-generic
OS Type: 64-bit
Processor: 1 × Intel Core Processor (Broadwell, no TSX, IBRS)
Memory: 3.8 GiB of RAM

ADDITIONAL INFORMATION
As can be seen from the specs above, I noticed this is a VM with only **one**
CPU core. I suppose this issue won't be noticeable in normal usage. All the
same, I think the point is valid that the slider and animation (with the
concomitant additional CPU usage) should appear only when the actual copying is
in progress.
