1. The button "View SQL" looks not like button.



2. The all lower button bar disappears when the window is not maximized.



Additional info:
Windows 10 Enterprise 21H1 x64,
PLSD ver. 15.0.2.2054 x64

We'll check it out.

Did you manage to reproduce this? Maybe you need additional information from me?

We have not yet been able to reproduce this. It seems to work fine under all conditions.

and if you choose „Windows 11 Polar Light“ style, still can't reproduce this (The button "View SQL" looks not like button)?
and it's a shame, but I haven't found how to fix it yet (The all lower button bar disappears when the window is not maximized.) because it does not depend nor on the color theme mode nor on the color theme mode style
my decision: use of „Color theme mode style“ - None (at least the first problem solves)
