[TC10.50b8 64bit] print preview: scroll with keyboard when no scroll bars

[white]

TC10.50b8 64-bit Print preview window.
With certain window sizes and no scroll bars, scrolling is still possible with arrow down and arrow right, and arrow left works half.
So I can scroll out of view when it should not be possible and I cannot scroll back into view.

See this video: gif

Used window size in gif:
PrintDX=575
PrintDY=843

Confirmed. It seems to be a bug in Lazarus. I'm already trying to intercept the mouse wheel in this case, and will have to write some code to catch the keyboard input too.

Tested 10.50rc1 64bit.

Problem with arrow right and left still exits.
So far I have not been able to reproduce the problem with arrow down.

Problem with arrow right and left still exits.

I can only reproduce it now when there is a vertical but no horizontal scrollbar. Do you get it also in other situations?

Mostly with vertical scrollbar, but also with no scroll bar. For example when using dimensions I gave earlier:

PrintDX=575
PrintDY=843

Tested OK using TC10.50rc2 64-bit.
