Summary0037985: HighDPI: "Replace next" dialog is not scaled correctly
DescriptionWhen enabling the "Prompt on replace" option of the Replace dialog on a HighDPI system (200%) the dialog that asks whether to replace the next location is scaled to large thus blocking the view of the location to replace (and reaching beyond the screen width in my case).
Additional InformationI have attached two fullscreen (scaled down) screenshot for once (one with HighDPI behavior the other with scaling done by Windows), cause this fully shows where and how the dialog pops up.
TagsNo tags attached.
Fixed in Revisionr64673, r64728

The buttons are now correct, but the dialog itself is still larger compared with the 100% one and thus blocks the text to replace.

Dialog position fixed in r64728.

The dialog is no longer in the way now, but the dialog itself is still significantly larger than with 100% (compare the attached screenshot to the one further up) and in my opinion that shouldn't matter if it's 100% or not...

I am attaching two screenshots taken of exactly the same dialog at 96 ppi (100%) and 144 ppi (150%). In my opinion they scale correctly (they look a bit different regarding text position, but this must be due to the icon which does not scale correctly - there is another report about this).

In your screenshot the dialog size appears too large relative to the text. Did you reduce the system font size? (I would not know, though, where this could be done on today's Windows).

Or was your IDE built with LCL scaling turned off?

You seem to use the docked IDE. I have no experience with it personally, so I cannot tell. But there are some reports about scaling issues with it. Could you try to temporarily work with the undocked IDE?
