[10.00β10] Rendering artifact in submenu items

[AGlezB]

There is an issue rendering submenus in dark mode. The issue is present all the way from 16x16 to 48x48 and more noticeable in higher resolutions.
Here you can see the it in 32x32:

This issue is also present in version 9.51.

Not confirmed. Can you provide more details, please?
- Windows version
- 32-bit or 64-bit Total Commander
- system scaling (e.g. 100%)

Edit: It seems to happen at higher scaling values like 150%. I think I found a solution now.

Hope it helps.

Still present in RC1 but a lot less noticeable.

It's not a bug! The white triangle is drawn by Total Commander. The black one is drawn by Windows AFTER I draw my menu content, so it cannot be prevented. What I do is draw the white one a bit to the left of the black one, so the user can see it - otherwise the black one would be drawn on top of the white one...

So it is a bug, just not a TC one. Thanks again, Microsoft.
The big traingles are no longer an issue since RC1 so we can consider this matter closed.
