TC10.50b1: on the Plugins tab of the search dialog, the buttons disappear

[Fla$her]

Win 7, classic theme.
After clicking the "More rules" button and reopening the search dialog, the lower buttons disappear, and an empty space appears on top of the TScrollBox element. Image: https://i.ibb.co/MfbxX2z/Plugins-tab-bug.png
After resizing the dialog or switching between windows, the buttons return, but before the next start of the dialog.

Also they will appear if you will roll the mouse cursor over the area where they should be.
Buttons one by one will slowly appear in their places.

Also command "Fewer Rules" does not work after that. You can click it, you can see that rules will be deleted one by one
BUT after reopening the form - all rules will stay on their old places.

Also the checkbox "Search in plugins" will also be first of all activated/triggered/turned on - after the opening this form,
but after that it will be turned off - automatically... Strange logic...

Confirmed

In my conditions, the mouse pointer does not affect anything.

Confirm.

It was the same in previous versions.

Yep, but i would like to treat it as a bug of visualization at least. Which should be fixed.
It is also basically strange that the visualization of this form is very much dependent on a computer power.
I've seen a thread on this forum more than once describing the slowness in visualization of this dialogue.
And the answer was - so "it's just a matter of filling all the form sub-elements with their data".
BUT! I've seen far more filled forms/dlgs that nevertheless show instantly on a screen.
The feeling is that the chosen programming language already imposes a SLOWLY significant constraint
on the speed of execution of machine commands. What happens next?

It's probably due to this change:
29.09.21 Fixed: Faster loading of multi-line options in Attributes dialog (plugins), Search dialog (plugins tab), and Custom columns dialog (32/64)

I'm not regularly using classic theme, so I'm grateful for all bug reports regarding it.

Fixed in b2

I propose to publish a bug report in a separate topic.
