我组合了此闪烁修复程序和此字体修复程序,然后我不得不添加一些我自己的代码以在绘画上启动一个计时器,以使TabControl在屏幕外和返回时均无效。
这三个都做到了:
using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public class TabControlEx:TabControl
{
    [DllImport("user32.dll")]
    private static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);
    private const int WM_PAINT = 0x0f;
    private const int WM_SETFONT = 0x30;
    private const int WM_FONTCHANGE = 0x1d;
    private System.Drawing.Bitmap buffer;
    private Timer timer = new Timer();
    public TabControlEx()
    {
        timer.Interval = 1;
        timer.Tick += timer_Tick;
        this.SetStyle(ControlStyles.UserPaint | ControlStyles.DoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);
    }
    void timer_Tick(object sender, EventArgs e)
    {
        this.Invalidate();
        this.Update();
        timer.Stop();
    }
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == WM_PAINT) timer.Start();
        base.WndProc(ref m);
    }
    protected override void OnPaint(PaintEventArgs pevent)
    {
        this.SetStyle(ControlStyles.UserPaint, false);
        base.OnPaint(pevent);
        System.Drawing.Rectangle o = pevent.ClipRectangle;
        System.Drawing.Graphics.FromImage(buffer).Clear(System.Drawing.SystemColors.Control);
        if (o.Width > 0 && o.Height > 0)
        DrawToBitmap(buffer, new System.Drawing.Rectangle(0, 0, Width, o.Height));
        pevent.Graphics.DrawImageUnscaled(buffer, 0, 0);
        this.SetStyle(ControlStyles.UserPaint, true);
    }
    protected override void OnResize(EventArgs e)
    {
        base.OnResize(e);
        buffer = new System.Drawing.Bitmap(Width, Height);
    }
    protected override void OnCreateControl()
    {
        base.OnCreateControl();
        this.OnFontChanged(EventArgs.Empty);
    }
    protected override void OnFontChanged(EventArgs e)
    {
        base.OnFontChanged(e);
        IntPtr hFont = this.Font.ToHfont();
        SendMessage(this.Handle, WM_SETFONT, hFont, (IntPtr)(-1));
        SendMessage(this.Handle, WM_FONTCHANGE, IntPtr.Zero, IntPtr.Zero);
        this.UpdateStyles();
    }
}
我不是创建者,但据我了解,位图可以绕过所有错误。
这是唯一可以为我彻底解决TabControl(带有图标)闪烁的问题。

ps。您将需要设置HotTrack = true,因为这也可以修复该错误
               
              
UpdateStyles设置完这些后您打过电话吗?记录不充分,但有时可能是必要的。
