Maybe I am wrong but it is not 2^16=65536?

You are right, sometimes is working sometimes not. But manual copy from text I think is working always. Switch back to "View as Form" and Paste on an other TCard.

I tried to Copy-Paste. It's working for me in 10.4.0.

I know it is frustrating but the result is same for me.

I tried with "Enable Flow Control Highlighting" disabled in 10.4 but I do not see any difference. It is a little slow only when bottom white space appears.

This issue is visible starting with D10.0 Seattle. Delphi XE-XE5 does not behave like this. But only when you see bottom white space.

D10.4 with i7-8700K For me anywhere in the source IDE CPU is 10% and very responsive. At the bottom when white space appears is 25% and a little slower but not an big issue. I rarely use scrolling when bottom white space is shown. I think this issues is tied to CPU speed + Number of LOC displayed when bottom white space is shown. No graphic card involved. Try to make the IDE height smaller in order to display fewer lines of code and for sure it will be faster and.... useless. Does it behaves better on host? I think does not.

I have almost the same configuration and bellow settings for display but I don't see any issues with scrolling. In VM is Windows 1903, on host 2004. I don't do any adjustments to the IDE after instalation. I will try to install Windows 2004 also in one VM and see. Update: I can install now Windows 2004 only on older VM's, on newer VM's with D10.3.3 and 10.4 I have this message "The Windows 10 May 2020 Update is on its way. Once it’s ready for your device, you’ll see the update available on this page."

THTTPClient doesn't work on Windows 7 and XP with SSL. On XP the message is "Server Certificate Invalid or not present" I don't find the message from Windows 7 but here is something about: https://stackoverflow.com/questions/50765476/delphi-tnethttprequest-tnethttpclient-works-on-win-10-but-not-win-7

Then it looks like it's deallocated at close. Maybe if you can debug and look in task manager. Put a break point in System._Halt0 and maybe you will see where is deallocated. Maybe deallocation is in finalization sections or some dll's. Maybe this MemoryUsed function can be called from watch list and compared with Task manager.

But reports something or doesn't report anything?

From what I see it's fixed like this: var p : PWord;

I can't reproduce this issue (the wrong value to be displayed across all records). What Delphi version do you use? Try to do a minimal example to reproduce this and post here. But why ?!? Your code is more convoluted and I don't see any benefit. Only trouble.

This procedure takes 76% of time in my case 2694 procedure TfrxPDFExport.ExportViaVector(const Memo: TfrxCustomMemoView); and was called because GapY was -1 if (Memo.ReducedAngle <> 0) or (Min(Memo.GapX, Memo.GapY) < 0) then ExportViaVector(Memo) With Gap=0 for some of memo components ExportViaVector() takes 44% of time and the report looks the same but the PDF is generated in 6 seconds vs. 13 seconds Edit: Better take a profiler and don't lose the time guessing.

Just tried 200 pages of something like this. 13 seconds.
