building fastreport 5.6 and 5.6.4 with lazarus 1.8

hello
i am trying to build fastreport with the latest lazarus, maybe it is too new or something and I am seeing issues.
1:UTF related functions are depreciated and lazarus can't find them. so I replaced a few of them with generic string functions. it seems OK
2:windows printer APIs are in winspool. added it to uses

for 5.6.4, there are some more issues. some windows drawing APIs are not found in gradient code, I gave up and went back to 5.6.

so I setup a connection with IBX to the firebird 3 demo database, drop in a frxReport and frxDesigner component.

with the following code I see a strange error

TControl.InvalidatePreferredSize loop detected
CodeTB:Toolbar Bounds=l=0,t=0,r=556,b=38.

IBDatabase1.Open;
IBTransaction1.Active:=true;
IBQuery1.open;
frxReport1.DesignReport();

    ok I tried with 5.6.4 again and instead of changing code, I added uses to fix missing functions.

    frxDesgnEditors.pas needs lcltype
    frxGradient.pas needs lclintf
    frxPreview.pas needs LazUTF8
    frxPrinter.pas needs winspool
    frxXML.pas needs LazFileUtils
    lazhelper.pas needs LazUTF8

    now 5.6.4 compiles but it is the same error. double click frxReport1 in a test application gives error
    TControl.InvalidePreferredSize loop detected
    CodeTB:TToolbar Bounds=l=0,t=0,r=566,b=38

    Found the root cause. it is the Use "LCL scaling (Hi-DPI)" option in project options. it is new in Lazarus 1.8 I suppose.
    not fetal but I still hope you guys will fix it.
